Animal and Person view roles about asm3 HOT 2 OPEN

The options should go under Remove->System->Remove fine-grained animal permissions, and Remove fine-grained person permissions (both set by default)

from asm3.

Like animalcontrol.py, animal.py and person.py will need their own reduce_find_results functions that are called by their find routines to throw away rows the user does not have permission to view. shelterview will need to call the animal one as well.

animal.py currently has a function get_location_filter_where_clause that does most of this, but it does it by some difficult logic and writing SQL. It would be a lot simpler if it were reimplemented as a reduce type function that throws away unwanted records the way that animalcontrol does.
