- Moved Windows code from DesktopPlatform module to Core.
- All other platforms aren't implemented yet, but should compile (fixes CIS).

- Added IDesktopPlatform::GetUserTempPath() and implemented it for windows
- Created SGetSuggestedIDEWidget class that handles whether to show a "Download X" hyperlink vs. an "Install X" button (depending on whether the platform supports on-demand installation)
- Analytics event added ("Editor.Usage.InstalledIDE") that fires whenever the "Install X" button is clicked
- Changed SourceCodeIDEURL_Windows in BaseEditor.ini from the VSC 2013 web page link to the installer download link (need to replace with perma-link once we have it)

#change Added (desktop) platform abstraction for checking if UBT is running. Fully functional for Windows, WIP for Mac and Linux (should work, but can give false positives)

Cocoa isn't an event-polling API as UE4 expects, so previously we were subverting the NSApplication's event handling to pretend that it was. When the engine wasn't running the event loop fast enough, such as when loading where it isn't processed at all, this resulted in unresponsive windows and Spinning-Beachball-Of-Death. That isn't very satisfactory & to some users appears as if the application has crashed. To address these deficiencies without further attempts to subvert Cocoa, the game is now punted onto a separate thread where it can run its own tight-loop, leaving the main thread to handle the Cocoa event run-loop. Events are captured by delegate objects, as Cocoa requires, but dispatched and handled on the game thread which makes Cocoa appear more like other platform APIs to the higher-level UE4 code.
This can all be disabled using the MAC_SEPARATE_GAME_THREAD define in CocoaThread.cpp.
