* morituri/common/task.py:

Add a 'described' method so listeners can get proper notification
	  of description changes, and update their description in between
	  progress changes.
	  Add a MultiCombinedTask that reports on progress over all tasks
	  combined.
	* examples/trm.py:
	  Add a playlist option to the example.  Still needs to store results
	  to pickles, preferably after each completed task.
	* morituri/common/checksum.py:
	  Add audioconvert to make sure we can trm ogg files.
