Feature: windowed mode option

[ghost]

Hey,
Currently it supports windowed mode but I'd like some improvements:

• option in the settings (just like in original ATI version)
• or to launch in the chosen resolution (not always in 720)
• or at least when being manually stretched to maintain the AR, and also update the resolution in real time on the screen (like TR2) would be great.

For people, who stream on a single display, windowed mode is a must.
Regards!
