implement running wine from polecat and more0.1.2

- implement running wine from polecat directly and pass all arguments to wine (default wine prefix is still $HOME/.wine)
- add command to list installed wine versions (lists all directories, needs to be improved)
- rename wine install to wine download
- replace deprecated support_compression_all with support_filter_all
- comment out DXVK command until its further implemented
- use PATH_MAX for strings holding paths
