editor: improved handling of tempo map changes

Browse Source 
This splits apart the actual signal handler from the work that needs to be done
to update the GUI in response to a tempo map change. This allows us to do the
visual update when we are manipulating the thread-local write copy of the map
during e.g. a drag operation.
