* 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. #BUN [CL 2329610 by Wes Hunt in Main branch]
