Live++ reads object files at startup for game modules, and assigns unique ids to each compiland (used to disambiguate static variables). When compiling the patch, these compilands are modified to reference a unique id for the unity blob, causing the variables to be reconstructed.
Solution is to generate a JSON file to each output directory containing object files containing the mapping, and to use that to assign compiland ids at startup.

Now stores the linker environment block in the live coding manifest, and adds it to the cache before executing the linker.

* Linker arguments for each hot-reloaded module where only being patched with that module's new name (and not *all* the new module names). Windows was unaffected by this, since it uses response files (which were being handled correctly).
* Loop to rename modules in the manifest was terminating after the first modified module was found. This prevented other modules from being renamed.

Disable signing on platforms that we wanted encryption enabled for by default (mobile mainly)
Add a warning if pak signing or encryption is enabled but there is no key, then disable the offending functionality for that build

* Removed code to invalidate makefiles when adding new source files. UBT should be reliable enough to make this determination itself nowadays, and ignored -invalidatemakefilesonly argument was causing modules to be recompiled.
* Fixed incorrect config section name when determining whether to allow hot reload from IDE. Now prevents hot reload from IDE when live coding is enabled.
* Added error message when trying to add a new class with Live Coding enabled.
* Added error messages when trying to start Live Coding after a hot reload has taken place.
* Added error messages when trying to hot reload with Live Coding enabled.

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

- Added a "-sign" parameter to enable signing for the given pak. The cached settings in the crypto.json file aren't used to enable signing any more.
- Encapsulated all signing and encryption keys in a single keychain object which is passed around, rather than individual keys
- Added some validation to UBT/UAT encryption config parsing so that if you enable any signing or encryption stuff but haven't generated a key, it'll warn and disable everything.

- Various changes for facial animation, screen recording, others
- ARKit and ARCore plugins were removed, as deemed "not ready"
