Big conversion of FStrings and FNames to FText.
Version bump to move some MaterialFunction UProperty from a TArray<FString> to TArray<FText> (some Engine assets are older than being allowed to auto-convert the UProperty)
Auto conversion of FName to FText (and back) now supported (as well as TArrays of those types).
Searching categories by both the localized string and the source string is now supported in Blueprints.

I fixed the crash found in the material editor, but discovered some rendering issues. Backing this out for now.

* 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.

#add Added UEdGraphNode::GetNodeNativeTitle to return a native title for a node.
#add Added UEdGraphNode::GetNodeSearchTitle to return the native and localized title for a node, together, for searching.
#add Can hold "alt" over a node (in the graph panel, or the palette) to see the native name of the node.
#ttp 331252 - Blueprints: Editor: L10N: Blueprints need to consistently show localized node names and when searching need to search both the localized name and the native name
