Gamepad friendly

[laromicas]

Hi, I think a great implementation can be the frontend to be gamepad and keyboard friendly, as I can only use it with a mouse.

There is some basic groundwork for XInput listening, but actual interaction is not as easy due the way I implemented the UI. I might fix that someday.

For a moment I was working on a "Big Picture" mode, exactly for this purpose. I've lost motivation to work on this project since and I wouldn't hope for this.

I'll keep this open, just in case somebody decides to try their hand at it.

My system is Nvidia shield with Kinoni Streamer and the PC running that program.
The first thing I looked for was gamepad support.
