- Patch by JonBob:

  Phase 2 of the menu system integration project. This unifies the interface
  used by admin and non-admin pages, and deprecates the _page hook in favor of
  explicit callbacks from menu(). Breadcrumbs, titles, and help text go away
  as a result of this patch; they will return in the phase 3 patch, printed
  by the theme.

- Flush cache after changing user permissions.  Patch by Gerhard.

- Removed duplicate call to drupal_page_header().  Patch by Moshe.

- Updated the INSERT statements at the bottom of the database schemes to
  reflect the bootstrap changes.  Patch #152 by Tom Dobes.

- Performance improvement: changed a LEFT JOIN to an INNER JOIN.  Patch #157
  by Gerhard.

   + block_list() (in block.module): returns an array of block objects for
     $region.
   + theme_blocks() (in theme.inc): uses block_list() and theme("block") to
     actually render them.

  Advantages:
   + Decouples blocks content and layout, allows block_list() to be used
     for non-output purposes (think "pull").
   + Unifies naming in theme.inc: render_blocks()) didn't really fit there.
   + Puts block_list() in blocks.module where it logically belongs.

- Removed some cruft from the Xtemplate theme.  Patch by Ax.
