Add opendesktop association of files for non-windows. NEEDS TESTING.

Add a misc folder to contain some files for attempting a local registration of hwengine against hedgewars demo and save files on request. Still needs the addition of the frontend code to mkdir -p in .local, copy the files, call update-mime-info and such

better support for wimpier i-devices

shorter strings for low-resolution friendliness

Updated mission translations
