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
- Show the "Server Add needs configuration" message whenever
there are no paths.
- Un-ajaxify the admin code to remove complexity and allow us to
update the status message as appropriate.
- Rename server_add_admin.html.php to admin_server_add.html.php
for consistency.
- Fix up form to properly display error messages
- Get rid of server_add_dir_list.html.php now that we're
non-ajaxified.
- Change delete <span> to an <a> for non-ajax world.
