New Revision: 382070

Log:
Clean up ConfBridge commands to account for wait_marked users

When ConfBridge was refactored to better handle the concept of marked,
wait_marked, and normal users co-existing in a conference (thereby implementing
a state machine for the conference), the wait_marked users were put into their
own list of conference participants, separate from the active users. This list
is used for wait_marked users when they are waiting in a conference but no
marked user has joined; normal users may have joined at this point however.
There are several AMI/CLI commands that affect conference users that were not
checking the wait_marked users list:
* CLI/AMI commands that mute/unmute a participant. In this case, wait_marked
  users have to remain in their particular state and should not be affected -
  however, the commands would return "Channel not found" as opposed to the
  appropriate error condition.
* CLI/AMI commands that kick a participant. An admin should always be able to
  kick a participant out of the conference.

This patch fixes both sets of commands, and cleans up the CLI commands slightly
by allowing them to complete a participant name (this was supposed to have been
added, but the function call was commented out and wasn't implemented).
