Added validation for listings, and bootstrap validation support
Added authentication check for backend actions
Added name to agent and agent drop-fown on listing form, made responsive
Listing form iterations: is_lease and is_residential are toggles, trains reworded, map is responsive, edit toggles reflect current value, wide save button changed to save/cancel
Fixed repeating images when less than 10, and now counting uploaded photos
Listing page iterations: Added photo tag and access instructions, redesigned description and details

Note: neighborhood instagram photos were already supported, this only
makes it more robust with a neighborhood model
