0.3 Release Candidate 1 - Now with Kinect v1 support

This is a release candidate for the next version, it doesn't have all features the release version will have and does contains bugs/crashes/etc, please report them!

Changelog:

• Added support for Kinect v1 (with support for dedicated background removal)
• You can now select which Kinect you want to use
• You can now duplicate Kinect sources and pay the cost of polling each device one time, no matter how many sources you have.
• Added "Body or depth" and "Body within depth" green screen modes
• Added support for Kinect v2 service process priority update
• Added a camera icon
• Fixed depth/IR size (it will no longer be stretched)
• Added dirty depth option (helps with flickering when little movement is involved)
• Added german translation (incomplete), thanks @pucgenie
• Performance improvements

What's missing:

• Kinectv1 near mode checkbox, for now it's always enabled.
• Kinectv1 high-res checkbox (output RGB at 1280x960 instead of 640x480, but at 15hz)
• Kinectv2 camera settings (this isn't an easy thing to do, will try to have it in 0.3)
• German translation is incomplete, it would be nice if someone could translate the remaining keys.
