Merge branch 'master' into 'master'

added drum-on, the android drum app

imported drum-on from github repo

notes:
 1. ~~not 100% sure about the category, maybe Multimedia is a better choice?~~
 2. build script will try to compile assets, but im not sure if it works on fdroidserver. if it fails it will download pre-compiled assets from github.
