- Avoid SQL queries if possible.

- Usability improvement: changed 'messages' to 'logs'.

Patch 5287 by Stefan: multiline help texts should become inside a single $output.

- Removed the hard-coded list of watchdog types.  The list is compiled
  dynamically and can be extended through the watchdog() call.  (Chris
  could use it to move the cron message to their own category.)

- Updated the calls to menu() to use MENU_HIDE instead of 1

  + removes the lots of pagers and indirect pager themeing
  + add the theme_pager() function, which should be called as
    theme("pager", ...) to get a pager.

- Corrected the context-sensitive help of the error messages.

- Patch 0178 by eafarris: moved the watchdog colors to CSS so they are themeable.

- Committed phase 4 of JonBob's menu system changes.

- 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.

- table(...) -> theme("table", ...)

- Small documentation improvements.

- Committed part 3 of Michael's help system improvements: removed the $help
  parameter from the menu() function.

     patch.

  because those of Moshe where not identical.

- Changed some INNER JOINs back to LEFT JOINs.  Patch by Gerhard.  Not tested
  by me.

  joins".  Patch by Gerhard.
