Subject: Switch from using SimpleUploader to using swfUpload as our flash
 based uploader.  This is modeled on
 http://codex.gallery2.org/Gallery3:Upload_UX but is not yet complete.

Notes:
* Changed #gProgressBar to .gProgressBar to support multiple progress
  bars on the same page
* Added a bunch of CSS to the "needs a home" section in
  themes/default/css/screen.css

+		*If false is returned from uploadComplete then the queue upload is stopped.
