1) Fixes Ticket #208
2) Fixes Ticket #190
3) Fixes an unticketed issue where two items could collide when
creating the thumbnail and/or resize. For example, loading a.flv and
a.jpg would have generated the same thumbnail image. This change adds
a random value to the name to avoid conflicts.
4) Added item::__set() to clear the relative path if the name changes
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
