3258d6e097 Fix issues related to unnecessary symbol reconstruction in Live Coding modules. Generating separate object files for updated compilands was resulting in symbols being assigned a unique compiland id.
Object files generated for Live Coding compiles are now temporarily renamed to their original versions until the Live Coding patch is generated, after which point they are restored. Would be preferable to incorporate this logic in Live++ directly and just read from the correct files, but the number of changes necessary to support it would make it difficult to integrate new versions.

308e27cdbb Live Coding: Fix support for lazy loading modules. Now passes UBT a list of modules that can be updated, and UBT fails the build and writes out a list of others that would be modified. Live Coding console then loads those modules and retries.

cf183af67c Integrating live coding feature (aka Live++) into UE4.
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
