Allow opening VLC rather than Chrome in vbrowser

This could be one way to bypass the browser's limited codec support--open VLC instead of chrome, which would allow playing virtually any video file.

With the network play feature this could help solve codec issues for users playing URLs

We could possibly make this work for users bringing their own files as well, by having the user stream upload their local file to the vbrowser instance, which might allow VLC to play as it uploads.

That said, if we're going to do this we might as well take the URL/video file, run it through ffmpeg, convert to something web-compatible and stream that to users
