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.

The AppFramework module is intended to be used for compound widgets and UI related classes that are too specific (not basic enough) for Slate, but also not Editor specific (reusable in non-Editor applications and games). The test suite has been moved in its entirety for now, but core widget specific test classes will eventually be split off and moved back into Slate, so that they can live alongside of their corresponding widgets.
Other changes:
- moved to "include what you use" scheme for SColorPicker
- broke out color picker related widgets that may be reusable
- added forward declarations to reduce header include dependencies
