The majority of asset reimport machinery is now held within UAssetImportData and FAssetImportInfo. This change allows us to remove the CachedAssetsBySourceFileName map from FAssetRegistry that was previously added to support auto reimport for 4.7.
The functionality of CachedAssetsBySourceFileName has been wrapped up in FAssetSourceFilenameCache, which sits on top of the asset registry in the editor.
This unification allows us to also consistently store the file timestamps and MD5 hashes of imported files. This subsequently allows auto-reimports to be ignored where a source content file has not actually changed (its MD5 is the same).
This addresses UETOOL-365 - Rework AssetRegistry changes to support auto-reimport

* 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.

- Window menu is now sectioned and labeled based on the current editor. There's now a local workspace root member in FTabManager and a workspace category in FAssetEditorToolkit (both are FWorkspaceItem objects). Individual editors attach their local category to the tab manager's local root. Workflow app modes have their own category members that are swapped out when the mode changes.
- Finally, the AssetEditorCategory of FWorkspaceMenuStructure has been removed entirely.
- Replaced the AddMenuSeparator() call in FTabManager::PopulateSpawnerMenu_Helper() with a section of the same title as the workspace category.
- Tab spawner menu entries for the local editor now properly show the icon of the associated tab. To accomplish this it was necessary to change FWorkflowTabFactory::TabIcon to be an FSlateIcon instead of an FSlateBrush*. All factory instances have been updated accordingly.
- Added & updated lots of icons! (those missing will be TTP'd)
- The nomad tab spawner section (named "General" in the menu) has been largely compressed into the Developer Tools submenu, which has also been organized into sections for readability.
- Unreal frontend options were also moved into a context menu within the General section
- Moved all experimental tools to their own section of the Window menu. When they're no longer experimental they should register as nomads in the appropriate category
- Undo history now under Edit menu

#ttp 345297 - NUX: Improve workflow for SME collision editing
#branch UE4
#change Modified Collision options to say 'Add' to indicate you're adding primitives and not replacing existing.
#change When adding a new collision primitive, it now does a quick check to see if there's another primitive that's the same and if so, moves the new one slightly so they don't overlap - the hope is that this also makes it clearer that you're adding primitives.
Note: Also includes change from 2280280 which enables Show Collision if it's modified
