Play a courtesy tone to the target of a SIP attended transfer when the transfer completes

The sample sip.conf shows setting ATTENDED_TRANSFER_COMPLETE_SOUND in a setvar example.  This setting only makes a difference if you are using builtin transfers.  This patch enables native SIP attended transfers to do the same thing.
I have tested making the transfer with and with out ATTENED_TRANSFER_COMPLETE_SOUND set.  I have also tried using both regular attended transfers and blonde transfers* and all behave as expected.

* mmichelson coined the term "blonde transfer" to describe the act of completing an attended transfer while the target is still ringing instead of using a blind transfer like Nature intended
