Added working but inefficient YQL query for geocoding
map_controller: multi_fql query to get friends and varied locations
		using lat/long from FB now
Updated location/friend models w/ validations
Refactored data queries
	   Query model to house FQL query actions
	   location and friend_loation_save models to parse & save data to db

	   map_controller amended to call constructor, house only request/response logic
Merge branches 'YQL_places' and 'master'
installed delayed_job_active_record gem & migrations
Implemented delayed_job around friend_location_save
	    this renamed to *_job
Merge branches 'delayed_job' and 'master'
