I did the first part, lock some showflags to be 0 or 1 in SHIPPING
If this causes problems for some applications (e.g. using showflag as scalability which they shouldn't) the user needs to update the code.
or we remove the lock from that showflag.
For editor or non shipping features it's fine to use the SetSHOWFLAGNAME() calls, they become NOPS in SHIPPING.
This is a performance optimization (when used in inner loop) and prepares for removing more

* 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.

Several other fixes for high res screenshot issues.
Default behaviour of screenshots with viewport-locked cameras is to only capture the actual viewrect, not including the black bars. Removed button for setting capture region to view rect.
