Okay, 6.6h should be pushed to GOG GALAXY now. This includes everything from normal 6.6h, and also restores the original "rainbow.xm" music to Ae6GOG.j2l, because Blade was able to contact the music trackers and get their permission to include it with JJ2+.

This is the first time I've directly pushed an update to the GOG one-click-mod track. I'm told that their QA will do a "very quick check" before publishing the 6.6h offline installer to the GOG website. After this, offline installers for future releases will "very probabl[y]" be published automatically at the same time as GALAXY updates, we'll see.
