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.

These variables (and their dynamic initializers) were being treated as new, rather than being linked back to their original instances. UBT now outputs a mapping of object files to their original unity object file during a live coding compile, which allows Live++ to disambiguate between new and reconstructed instances.

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

* 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.

* Compile dropdown now just contains a checkbox for enabling live coding.
* Compile dropdown has a link to open the editor preferences window.
* Live coding can be enabled from the editor settings window.
* Option to show the console on startup is now folded into the startup mode.
* Options in the editor settings window are greyed out unless live coding is enabled.
