[svn r8093] Added QM model and parser. Had to merge models_cave.py and models_logbooks.py into models.py. This is because logbook entries now have an optional foreign key to caves, and QMs have a required foreign key to a logbook entry of the trip that created them. So, the two files became circularly dependent.

Also, the urls for the person model now allow lookups using their actual first and last name in the url instead of the primary key. We should do similar things for all models, maybe even using the url as a search which results in a page with multiple model instance results if the input is ambiguous (e.g. they only enter a first name).
