Subject: implement DXVK functionality, renamed installed to list-installed,
 […] - main DXVK functionality implemented, installing (etc.) can be done now 
  this adds a dependency on the system installed wine to modify the registry
 but that isn't too huge of an issue right now - <command> installed has been
 renamed to <command> list-installed to be more user friendly - comments have
 been improved
