SkyNx Stats and variable bitrates!

Changes:
Allowed some bitrate variation to help those with stuttering.
Fixed the audio filter making the sound a little quite and muffled.
Automatically set enconding buffer based on chosen bitrate.
Add fps and bitrate monitor.
Added a stats panel with a FPS graph.
Added better status bar text.
Greately reduced the size of the streamer.
Fixed improper tooltip.

Notes:
The streamer has updated but the app has not. You can use the V0.6 releases app.
