Adding settings for connection services.

1) List all connection services in phone account settings.
2) Add icon to the settings listings
3) Adds code for SIP phone accounts to handle the standard
   telecom CONFIGURE_CONNECTION_SERVICE intent. This means
   that when a user clicks on the listed SIP account, they
   will be taken to thats SIP profile's settings.
4) Added code to SipProfileDb to retrieve a single profile
   by Uri.
5) Updated SipSettings to refresh list onResume(). This
   allows deletes and updates made from the phone account
   list to reflect the legacy Sip Profile Setting activity.
