More fixes here. First, fixed binary path parsing for profiles,
so you should be able to add a profile on macOS now. Only one
requirement - you should add Quake3-UrT.x86_64 file, which located
inside Urban Terror's application bundle, under Contents/MacOS
directory.
Fixed the way we call Urban Terror on macOS and tested it. Should
work now flawlessly.
Bumped to 0.1.0-beta2, and mac-only release for now.
