Safety checkin right before we blow everything up...
More progress towards a working file uploader
image upload progress
Bug fix: user can now add a photo to a meal that was previously saved without a photo.
Fixed a few bugs with display and overwriting saved images as null
User can now remove an image and make a meal have no photo associated with it
Bug fix: viewing a meal that has no image associated with it will no longer display the image of the previously viewed meal
Fixed annoying selection bug in admin list. Clicking anywhere on an item's row is now a valid way to select an item in the list.
Bug fix: No more stale image preview when changing the image of a meal that already has an image.
Refactor: removing unused code and bits left over from building fileUpload, removing comments, reorganizing and renaming things before moving forward
More minor refactoring, removed redundant and unused code that was written back when the admin page actually uploaded a file separately from saving it to db.
