app_sendtext
------------------
Support Enhanced Messaging. SendText now accepts new channel variables
that can be used to override the To and From display names and set the
Content-Type of a message. Since you can now set Content-Type, other
text/* content types are now valid.

app_confbridge
------------------
* ConfbridgeList now shows talking status. This utilizes the same voice
detection as the ConfbridgeTalking event, so bridges must be configured
with "talk_detection_events=yes" for this flag to have meaning.
* ConfbridgeList now shows talking status. This utilizes the same voice
detection as the ConfbridgeTalking event, so bridges must be configured
with "talk_detection_events=yes" for this flag to have meaning.
* ConfBridge can now send events to participants via in-dialog MESSAGEs.
All current Confbridge events are supported, such as ConfbridgeJoin,
ConfbridgeLeave, etc. In addition to those events, a new event
ConfbridgeWelcome has been added that will send a list of all
current participants to a new participant.
