Fixed some typos
Added basic find-or-create location importer from map.ucf.edu; added location_id to locations to track locations that have been imported:
Length checking for import ids. Better safe than sorry.
Save empty room value as empty string instead of None
Added setting to define domain name for map.ucf.edu; separated domain name from location_data_url
Updated locations in review to use span.badge to show location count
Pagination improvements
