fixed bug with naming files (original_filename doesn't exist when using remote upoad from fb files) in images_controller.rb
cleared out uploads folder of images
conflict with deleted images in tmp folder. have deleted from dev branch.
resolved conflict with dev in set_name method in images_controller
tested upload from fb and generate mosaic. all works. conflic resolved
added imagepicker to montage new form
added another select menu on new mosaic form so that user can select the Target image. Updated mosaics.js so that add/remove all tiles buttons only apply to the tiles select menu and not the target select menu
