Intro 'bounce' is driven by a float curve asset.
Because of rich text not working very well when zoomed at the moment, only the border is zoomed when animating. The content has the inverse zoom applied to it to counter this.

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.

Arguably sweeping a problem under the rug for now, but NullWidget added by STutorialRoot is apparently causing problems on Linux, so ability to disable UI (per platform) is helpful in the short term.

NOTE: Old tutorials not deprecated (yet), but widget highlights in old tutorials will stop working with this change!
Added new Blueprintable UEditorTutorial object.
Added suite of widgets and details customizations to display tutorials.
New system is available on command line switch -NewTutorials.
Slate changes:
Tag names are now stored in SWidgets, rather than simply being discarded.
Removed STutorialWrapper in favour of using Tags.
Added Tags to more multibox widgets, so virtually all can now be picked.
Added SWindow::HasOverlay so we dont attempt to add overlays to widows that cannot have them.
