- finishing off ui changes to file upload widget based on linton's updated mockups.

- fixing various upload related bugs (resize issue, not handling file exists exception, not attaching uploaded files to workflow, loosing some of the uploaded files, and probably some more).

- reusing upload_helper.js code from xforms.js.  added facility for having the javascript return page return an error and file type image to support xform - doesn't effect other usages (create form).
