Complete write of compiler/signer

Completely rewrote how recompiled apk files are stored so to not clutter
up the place-apk-here-for-modding as that folder is just for storing
unmodified apk files.

Updated the signer location to match up with the changes to how modified
apk files are handled
Merge remote-tracking branch 'origin/Experimental-RELEASE' into WIP-2.0
