Add support for the Open Arena missionpack


I know this missionpack is a bit prototypical (for my taste at least), but is it possible to give Spearmint support for it? Should be named something like “oamissionpack” or “oamp” or something like that. I would like to see support for it in the forseeable future, @zturtleman.



Thanks @zturtleman! So it’s set up as missionpackoa then…


It seemed like missionpackoa fit with the baseoa naming.


That makes sense (the naming scheme at least)…
