Add option to use Ringtone looping API in Telecom config.xml

Currently AsyncRingtonePlayer will check every 3 seconds to see if the
ringtone has stopped playing and restart it if it has.  Adding a config
option so that we can isntead opt to just set the ringtone to loop by
itself.
Default is to use existing 3 second handler check.
