[mediacapture-screen-share] Option to exclude cursor from video stream

mhofman has just created a new issue for 
https://github.com/w3c/mediacapture-screen-share:

== Option to exclude cursor from video stream ==
Opening spec issue based on [Chrome issue 
463423](https://code.google.com/p/chromium/issues/detail?id=463423).

Some applications might want to receive a video stream of the screen 
share that doesn't include the cursor.
I believe adding a constraint for this would be an easy way to provide
 this feature.

Where things get trickier is that such applications might want to 
receive the cursor position programatically instead. This would 
require extending the `MediaStreamTrack` object to dispatch events 
about the cursor position.
Furthermore, applications would also want to get the cursor image, 
which is tricky since not all cursors are simple bitmaps that are 
alpha blended, some are xoring their background (text selection cursor
 on windows is the main example)

In #35 I'm already suggesting extending the `MediaStreamTrack` object 
to expose a "pixel ratio" attribute of the stream. I'm open to 
alternatives but it sounds like we need a consistent way to expose 
"metadata" about the screen sharing stream.
