Is your feature request related to a problem? Please describe.
Users should be able to pause video and audio in a window that does not have focus.

Describe the solution you'd like
We should put play/pause buttons in the title bar when the window does not have focus so the user can pause/play with out giving the window focus.

@thenadj I think this was dropped from the title bar spec?

@bluemarvin Good catch! I'll create this and will post here when it's done. Is this a 1.4 feature?

@thenadj preferably yes, if we can get it done quickly!

Attached is the updated UIS plus the two icons for the button.
