Make WindowsDevice for Sonar

Summary:
This diff adds the ability for a windows desktop app to be a selectable device for Sonar.

just to over-communicate what I'm thinking regarding the logging: windows system logs don't have a lot of valuable information in my experience, and there is a ton of garbage, but there is probably a way to tap into that if we want.

however, I was thinking that redirecting stderr/stdout from every connected process would be useful. i.e. OVRServer could register a log plugin and it would write to the device's log output. not sure if this would be better than just having a logger plugin. This is probably a pretty naive question and this probably isn't the place to have this conversation...but here we are :)
