UETOOL-332 - Collections 2.0
Converted FFrontendFilter_Text to use FTextFilterExpressionEvaluator directly (rather than via TTextFilter), as this allows it better control over memory re-use (in this case, re-using an array of collection names, as well as some strings).
Added FTextFilterString, which is used internally by the compiled text filter, and also by the comparison functions. This stores the string given to it as uppercase, which allows us to quickly perform case-insensitive string comparisons since we can actually do normal case-sensitive comparisons instead as everything is uppercase.

UETOOL-332 - Collections 2.0
UETOOL-369 - Want nested collections with collapsing
We now have version 2 collections which maintain a persistent GUID for each collection. Existing collections will be lazily updated to this version when they need to be re-saved.
This GUID is used by child collections to keep track their parents, and the collections view (as well as the quick asset management) now show a tree of collections. Collections in the main collection view tree can be re-parented via drag and drop.
Performing Content Browser searches against a given collection will also test to see if an object exists in child collections, and the asset view will now show you folder entries for child collections when viewing a parent (if folders are enabled in your Content Browser view settings).

UE-14641 - Fix PushMenu() to use QueryPopupMethod()
Pretty big refactor
Adds IMenu as way to identify menus. Replaces referring to menus as SWindows.
Lots of uses of PushMenu() fixed up to match new API

UETOOL-332 - Collections 2.0
This avoids the need to repeat the module name throughout the code (and potentially performing an FName look up each time).

UETOOL-332 - Collections 2.0
This avoids conversion from FString to FName when dealing with the collections manager API (which gave the collections view the data as an FName to begin with).

UETOOL-332 - Collections 2.0
UETOOL-370 - Ability to assign many collections to a single asset very quickly
The collections view now provides check boxes next to each collection. These can be used to quickly add or remove a large selection of assets to or from a collection.
This feature is also available in the Content Browser via the asset context menu. The "Collections" section now contains a sub-menu which lists the available collections, and allows you to quickly add or remove the current selection to or from a collection.

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.

* 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.
