#jira UE-12430 - BSP brushes that have been brush clipped cannot be copied and pasted between maps
#jira UE-12122 - Editing duplicated BSP brushes also edits the original brush
The new UModel is created as an inner object of the new Brush, meaning that it has no external path and hence imports correctly.

#jira UE-7507 - Vertex editing 2 BSP brushes simultaneously reverts to local movement for brushes that have been rotated

#jira UE-5794 - The translation widget uses a BSP's initial position when Geometry Editing after rotating

* 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.

Breaking changes include:
* Rename of GEditorModeTools -> GLevelEditorModeTools to signify that it applies only to the level editor modes
* Addition of FEditorModeRegistry, responsible for managing and creating new editor modes. Modes are no longer registered with an instance of the mode, instead with a mode factory that is able to create a new mode of that type.
* Editor modes now operate on FEditorViewportClients rather than FLevelEditorViewportClients
* Added ability to specify an FEditorModeTools when creating an FEditorViewport
Moved component vizualiser manager handling outside of individual editor modes, and into FLevelEditorViewportClient. This should make it easier to transplant in future.
This work addresses TTP#334640 - EDITOR: Investigate making editor modes a per-'editor' concept

#summary Fixed not being able to set camera movement speed in toolkit viewports
#change Moved anything to do with camera speed in the level editor viewport settings into the level editor viewport client and added a transient camera speed setting to all other viewports.
