Config Backends

Currently, the only 'config backend' that freepbx supports is the asterisk .conf files.

However, it should be possible to modify retieve_conf to be able to write to various other "backends":

• Asterisk .conf (currently supported)
• Asterisk-realtime (#629)
• OpenPBX
• YATE
• FreeSWITCH

etc..

This would likely be configured in amportal.conf.
