Add output caching for Forge 1.13+.

CHANGES
 - Forge installer is no longer stored to the work directory. It is now stored in a cache folder corresponding to the artifact version.
 - Installer output is now cached by default
 - Added options to generate distro.
   - --discardOutput Delete cached output after it is no longer required. May be useful if disk space is limited.
   - --invalidateCache Invalidate and delete existing caches as they are encountered. Requires fresh cache generation.
   - Both options are false by default.
 - To invalide a single version, manually delete the folder.
 - Old functionality is essentially g distro --discardOutput --invalidateCache.
