steam - special workaround for bad steam games so they match desktops

many steam games don't provide much in properites - not enough to
match to a desktop file. the only thing that actually consistently
works is to use the STEAM_GAME property and match thyat to the uri
provided to the steam command in the exec of the desktop file. this
actually can work. nothing else works reliably across the board.

and man can games be horrible and playing nice with desktops and
having poor properties. even steam itself is not good. i had to add a
workaround for that too to match steam-runtime explicitly. :(
