- Fixed bug #6048: display footer in theme chameleon.

- Fixed the bullet icon.

- Patch 5968 by Chris: the background-image line has a superfluous 'pure' in
  the pathname, causing the theme to fail to find the background image and
  issue errors to the watchdog log.

- Changed the directory structure of theme chameleon.  Each template is now
  in a subdirectory.  This makes it easier to clone/fork an existing theme.

- Patch #5567 by Goba: fixed t() functions, cleanup of locale module's help,
  fixed translation issues in taxonomy module, etc.

- Patch 5140 by Moshe: removed the theme("header") and theme("footer") functions.

 - Adds drupal_set_header() and drupal_get_headers().
 - Cache now stores custom headers.
 - Replace theme_head() with drupal_get_html_head(), added drupal_set_html_head().
 - Added RSS autodiscover links to node, blog and taxonomy pages.
