browser (calls): screen sharing implementation: - the new screen sharing button toggle screen sharing state - the button reflect the screen sharing state (green crossed when not sharing, red uncrossed otherwise) - the screen sharing stream replaces the camera one, and vice versa. No re-negociation is needed. - stopping the sharing through browser's dialog is supported - the screen sharing button is only visibile if supported by the platform rel 432
