Updated fixture file
Add index_featured boolean to Spot model

Add a new "featured" switch for use on the front page only, so that the regular "featured" spots can be different on the other pages, .e.g. media, work, etc.
Renamed CityOfEdmonton.jpg image file
added conditional for if spots exist to get rid of nasty error.
