Known minor bug: If multiple windows are open with pulses animating, only the one that is given the "dismiss all" command will stop animating. The others will continue until their windows are closed and reopened, or they are dismissed individually.

Always remind users about tutorials until they complete the tutorial or explicitly dismiss it (UE-9550)
- Previously, even opening a tutorial once would prevent the reminder beacon for that tutorial to show again, ever.
- Now, the beacon will be hidden for the remainder of that editor session and reappear the next time, unless the user completed the tutorial
- The user can also right click on the beacon and choose to "Don't Remind Me Again" which will prevent it from appearing in the future for that specific tutorial (no change in behavior)

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.

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.

Tutorials browser now always appears on the mainframe. This avoids the browser appearing on small torn-off windows if content is torn off while a tutorial is in progress.
Also fixed crash when opening a browser from a widget that used to be docked to anotehr tab (weak window pointer was invalid at this point).
TTP# 347014 - EDITOR: TUTORIAL: If a tab is undocked while being referenced in the "welcome to the unreal editor" tutorial, there will be two instances of the tutorial text

You can access all context-sensitive options via the right-click menu.
Also exposed the ability to refresh available tutorials (as they may have bene reloaded since).
