While the asset registry is loading we need to refresh tutorials as this is the only mechanism by which they are picked up by the browser.

Introduces the concept of "Active Ticking" to allow Slate to go to sleep when there is no need to update the UI.
While asleep, Slate will skip the Tick & Paint pass for that frame entirely.
- There are TWO ways to "wake" Slate and cause a Tick/Paint pass:
1. Provide some sort of input (mouse movement, clicks, and key presses). Slate will always tick when the user is active.
- Therefore, if the logic in a given widget's Tick is only relevant in response to user action, there is no need to register an active tick.
2. Register an Active Tick. Currently this is an all-or-nothing situation, so if a single active tick needs to execute, all of Slate will be ticked.
- The purpose of an Active Tick is to allow a widget to "drive" Slate and guarantee a Tick/Paint pass in the absence of any user action.
- Examples include animation, async operations that update periodically, progress updates, loading bars, etc.
- An empty active tick is registered for viewports when they are real-time, so game project widgets are unaffected by this change and should continue to work as before.
- An Active Tick is registered by creating an FWidgetActiveTickDelegate and passing it to SWidget::RegisterActiveTick()
- There are THREE ways to unregister an active tick:
1. Return EActiveTickReturnType::StopTicking from the active tick function
2. Pass the FActiveTickHandle returned by RegisterActiveTick() to SWidget::UnregisterActiveTick()
3. Destroy the widget responsible for the active tick
- Sleeping is currently disabled, can be enabled with Slate.AllowSlateToSleep cvar
- There is currently a little buffer time during which Slate continues to tick following any input. Long-term, this is planned to be removed.
- The duration of the buffer can be adjusted using Slate.SleepBufferPostInput cvar (defaults to 1.0f)
- The FCurveSequence API has been updated to work with the active tick system
- Playing a curve sequence now requires that you pass the widget being animated by the sequence
- The active tick will automatically be registered on behalf of the widget and unregister when the sequence is complete
- GetLerpLooping() has been removed. Instead, pass true as the second param to Play() to indicate that the animation will loop. This causes the active tick to be registered indefinitely until paused or jumped to the start/end.

Where dynamic event names were being constructed from tutorial assets, now reworked events to add a dynamic parameter.
UE-4978 - Restructure Tutorial Analytic Events

* Moved Slate.h into SlateBasics.h and began shifting less commonly used headers into SlateExtras.h.
* Slate.h now simply includes SlateBasics.h and SlateExtras.h.
* Slate.h includes a deprecated warning now to indicate that SlateBasics.h + specific includes should be used instead.
* Moved dozens of inlined functions using Slate widgets into .cpp files to avoid header dependencies.
* All code samples now include SlateBasics.h and SlateExtras.h so future shifts will not break most those projects, but not trigger the deprecation warning of including Slate.h.

Tweaked styles and layout to better suit a tab.
Also fixed browser not showing some tutorials if all assets are not yet loaded.
Progress is now updated periodically as the browser can be now open while a tutorial is in progress.
TTP# 347956 - TUTORIALS: Selecting More Tutorials can hide Tutorial Browser

TTP# 347884 - EDITOR: TUTORIALS: text does not expand when maximizing the window
The auto-wrapping allowed the text block to shrink when the window was shrunk, however the sizers were set to align their content left horizontally (rather than fill, which is the default) meaning that the text block was never allowed to grow again once it had shrunk.
A better way to achieve this is to set the sizer slots to fill, and then use the text justification on the text block to control the text location - thankfully both of these are the defaults.

If we have a search string we should search all categories starting at the current context, rather than just one level deep as before.
Also fixed search text highlighting to be consistently coloured and to show up for rich text content.
TTP# 347534 - CRITICAL: TUTORIALS: Search bar only shows results for currently displayed tutorials
[CL 2312725 by Thomas Sarkanen in Main branch]
Displays crumbs according to the current navigation filter.
TTP# 347533 - TUTORIALS: Display tree path in Tutorial Window

Also allow tutorials to be hidden from the browser if necessary
TTP# 347111 - TUTORIALS:Tutorials browser shows MacroLibraries based on EditorTutorial class
[CL 2305308 by Thomas Sarkanen in Main branch]
Shows when a tutorial has been completed.
Also added tooltips explaining what the icon means & a tooltip for the restart button.
[CL 2302400 by Thomas Sarkanen in Main branch]
Tutorial contexts for IOS/Android/Whatever are now hooked up (console setup ones are still missing).
Analytics added for tutorial usage in various places.
Added ability to reset tutorial state with -ResetTutorials command-line flag.
Cleaned up some unused code (still a lot more to come here!).
[CL 2302314 by Thomas Sarkanen in Main branch]
Tweaked padding and button styles so the layout is more consistent.
Add ability to display textures as icons in the browser (for categories and tutorials).
[CL 2292442 by Thomas Sarkanen in Main branch]
Icon is only visible if content is available for the editor in question.
Split editor settings into two groups - one is persistent settings and one is progress/state.
Tutorials record their dismissed state, so users can permenantly disable the 'nag' for a particular tutorial.
Tutorial content now solidifies when the mouse is hovered over it, so it can be made easier to read.
Fixed crash on startup if an intro tutorial was displaying rich text.
Also fixed crash for TTP# 345094, where a zero-length tutorial was being accessed.
[CL 2275934 by Thomas Sarkanen in Main branch]
Fixed visibility issues where hyperlinks could not be clicked.
Implemented BP functions for tutorial stage completion etc.
