HotKey to Mute Sound

[mikegonzalez2k]

Currently the only way to Mute Sound is to go into the Sound Settings and click the checkbox to "Mute Sound".
It would be nice if there was a quicker way via a HotKey.
Please create a HotKey which will toggle this checkbox.
Doing this would allow users to quickly mute their game audio if they have a call, etc.

I've added a hotkey to the most recent testbuild.
