* The original .uproject file is now compiled into monolithic executables when Live Coding is enabled. This allows invoking UBT with the original project file when the executable is staged to a different directory. This parameter can be overriden via the LiveCoding.SourceProject cvar.
* The original engine directory is also compiled into the executable. This allows finding the console executable path without having to enter it manually via the LiveCoding.ConsolePath cvar.
* If an exact match for a binary filename is not found, try to find a match by name only. Also required to support staged builds for 'Launch On', etc...
* Add a LiveCoding.Compile command to trigger a compile from the console.

Allows fast iteration of C++ changes without restarting the application. To use, select the "Live Coding (Experimental)" mode from the drop down menu next to the editor's compile button, or type "LiveCoding" into the console for a monolithic build. Press Ctrl+Alt+F11 to find changes and compile.
Changes vs standalone Live++ version:
* UBT is used to execute builds. This allows standard UE4 adaptive unity mode, allows us to reuse object files when we do regular builds, supports using any build executor allowed by UBT (XGE, SNDBS, etc..).
* Adding new source files is supported.
* Custom visualizer for FNames is supported via a weakly linked symbol in a static library (Engine/Extras/NatvisHelpers).
* Settings are exposed in the editor's project settings dialog.
* Standalone application has been rewritten as a Slate app ("LiveCodingConsole"). There is an additional option to start the program as hidden, where it will not be visible until Ctrl+Alt+F11 is hit. Similarly, closing the window will hide it instead of closing the application.
* Does not require a standalone licensed version of Live++.
Known issues:
* Does not currently support class layout changes / object reinstancing
