Add easy WINE and or Proton integration on linux.

[KBOX1234]

On Steam, there is the Proton compatibility layer that makes it easy to run Windows games on Linux. However, on the Drop client, there is no easy way to configure it to use Wine/Proton for launching Windows-only games.

A possible solution would be to add a setting that allows Drop to automatically run Wine/Proton for Windows-only games, or at least provide more advanced configuration options for bootstrapping games with Wine/Proton. Ideally, both options would be available.

If you get a chance, give the 0.4.0 release candidate a go - we've built out some pretty decent Proton compatibility. Keep in mind it's a little rough around the edges because of the release candidate, but I'm hoping to fix it up soonish and get it out.
