Adding photo functionality to harvests
merging the schema changes from finished plantings and making the timestamp newer, then making the styling on harvest photos match the new styling (no li) on planting photos
including all the new files needed for harvest photos, this time
whitespace fixes and um oops no there shouldn't be a secret key in that config file
removing unneeded photo-related files
Delete unused photos

Make sure the models are setup so that if a photo is not used for
anything, it's removed from the system.

Also wrote a rake task (which should be run on deploy) to remove older
unused photos.
