Title: making sure existing image is not deleted upon save

Fixes #298 by implementing recommendations from http://www.jasny.net/articles/jasny-bootstrap-file-upload-with-existing-file/ and an additional check in the edit_event view. The chance detects event events that don't touch the image, making sure it's not deleted unless the user clicks the Remove option.
