UETOOL-213 - Minimize Slate FString -> FText conversion (remove SLATE_TEXT_ATTRIBUTE)
This fixes any editor/engine specific code that was passing text to Slate as FString rather than FText.

Not changing the existing behavior, although unsure whether it matches the intent in some cases.
Rule of thumb: when || and && are in the same scope, they are evaluated as if && was in parentheses
E.g.
Pointer && Pointer->Foo() || Pointer->Bar()
is evaluated as
(Pointer && Pointer->Foo()) || Pointer->Bar()
(I fixed such cases in changelists before this one as they were certainly unsafe).

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
