 The signal monitor reports the status of tuning events to the
 mythfrontend.  By adding the channel change process to this list of
 events, the user gets immediate feedback during a channel change.  If the
 channel change fails or takes a long time, the user can see this, and
 choose to select a different channel or abort LiveTV.

 Mythfrontend has a 15 second timeout before it gives up waiting for the
 backend to send it data.  Some external channel change scripts can take
 over 15 seconds, which means they must be run in the background to prevent
 a timeout.  However, if a signal monitor is desired, the channel change
 could not happen in the background because the monitor needs to know when
 the channel change is complete.  By moving channel change monitoring into
 the "signal monitor", this problem is solved.

 Note: With this change, any pre-existing external channel change scripts
 which ran in the background, must be modified to run in the foreground.
