Presence notificaton for IP2IP
DBUS methods for publishing presence
Adding phone status (ringing,on the phone,ready)

This code enable presence subscription / notification based on Asterisk hint mechanism.
The presence of a SIP account will be automatically pushed by Asterisk server.
DBus interface in CallManager (subsribePresence) is added to subscribe the presence of a buddy uri for an accountID.
Then presence notification are received in buddysip.cpp. Callback to UI must be there implemented.
Lot of commented code is still in the code. Work must be done to clean it.

Namely by telling the client who triggered recording whether or not
recording has started.

This can be used to query whether a callID exists before trying
to get lots of information on it. This avoids false positive error
messages as well as DBus traffic.

Also, removed superflous second getSIPCall method
