initial commit

Added dropzone to core
Implemented  dropzone on upload.php, templated to look just the same
with some added embelishments.
Removed uploadify css

Mostly functional, does not prompt for overwrite existing files, some
issue with ajax page reloading ( deletes are no ajax etc ), mostly due
to jquery live issues
remove all traces of uploadify
