New dated Editors' draft v20140619

Hi

A new dated version of the editors' draft is available.

Dated version: http://dev.w3.org/2011/webrtc/editor/archives/20140619/getusermedia.html
Living document: http://dev.w3.org/2011/webrtc/editor/getusermedia.html

Changes include:
	• Clarified that skipping of optional/advanced ConstraintSets is only permitted if they cannot be satisfied, not merely because the user agent wishes to.
	• Bug 25855: Clarification about conformance requirements phrased as algorithms
	• Bug 25803: Mark section entitled "The model: sources, sinks, constraints, and settings" as non-normative
	• Bug 24015: Add callback to indicate when available media devices change (introduced Navigator.mediaDevices)
	• Bug 25860: make sure we have a bug to have a getTracks that gives you all the tracks
	• Bug 25884: applied constraint syntax consensus as realized in June 9 WG email from Peter Thatcher.
	• Moved getSupportedConstraints() method to MediaDevices object.
	• Added stricter requirements on the getSupportedConstraints() return value.
	• Added issue note in Constrainable Pattern section that ideal is not yet defined.
	• Added issue note for applyConstraints that how multiple unorderedConstraints are to be satisfied together is not yet defined.
	• Added informative notes that WebIDL discards unknown required properties and that application authors need to use the getSupportedConstraints() method.
	• Cleaned up the MediaStream API intro section (mainly MediaStream behavior that have moved to MediaStreamTrack).
	• The concept of MediaStreamTrack with a detachable source is now used throughout the spec (removed language saying that a MST could be disassociated from its track).

Please review and provide feedback.
