mod_voicemail: Add 2 new profile settings, db-password-override and allow-empty-password-auth.  By default, they have value of their previous behavior.  If db-password-override=true, the db password will only be used if present, if not present fallback to the xml config file vm-password.  If allow-empty-password-auth=false, it will disable login via a authentication method if there is no password set in the user account (This wont affect voicemail_authorize=true login).

mod_protovm: Fix the set password ivr. Made the terminate key configurable for digit capture, and a few ident and other small changes

switch_channel: When in a dialplan hunt and we have a custom caller_profile, ${destination_number} and other variable kept the previous value of the original dialplan parsing.  This correct this so it take the custom created caller_profile for that hunt

mod_protovm: Add premitive tone playback before recording.  Need to make this optional and configurable

mod_callcenter: More changes to be more friendly/compliant/respectful with loopback channels.  Brought to you by François Delawarde

mod_protovm: Add Message Forwarding Capability (Require a mod_voicemail patch that will follow in the near future)
