Added Sound and Palm detection

-Sound I know it works, it plays, it's just we're not in a position to
play it yet since there's not way to 'select' stuff

-The palm thing, i have code right now to check whether it works or not,
I'm getting errors on the GUI side about:
unable to load the metadata for 'Microsoft.Samlpes.Kinect.WpfViewers'...
the type 'my:kinectdepthviewer' was not found...
the type 'my:kinectdepthchooser' was not found...

didnt have this error before
