Fix comment
Adds audioSenders and videoSenders fields to CallPeerMediaHandlerJabberImpl.
They keep the current 'senders' value for the Jingle session with the
associated CallPeer. The reason for adding these fields, instead of using the
already saved ContentPacketExtension in {local,remote}ContentMap is that it is
not clear which one should be searched.

Changes AbstractCallJabberGTalkImpl#modifyVideoContent(), so that it updates
the Jingle sessions of the Call to reflect the current state of the the video
content of the Call.

The "direction" that the Jingle session for a given CallPeer should have is
calculated in CallPeerJabberImpl#getJingleDirection().
