added save and add new button to story controller
added dropoff location to shelter form

this is single location only - I hope this is what we were discussing..
fixed a bug for dropoff locations

creating a new location from scratch was creating a fatal error -
invalid array. have rectified it now.
changed dropoff locations to 1 - many relationship

will need to import location notes into the dropoff location table for
each shelter
