documentation fix

lowres theme data for iphone compatibility

sound for mortar

a lot of stuff: - added an autoupdater option * works in mac osx only * the xml file should be hosted on official webserver * checkbox could be moved in a "updates section" of the option page * only english and italian translation provided for new option - reverted openalbridge type for compatibility - german translation fix

other indentation, binding and miscellaneous fixes to openalbridge
