Marking code as beta 1 in preparation of the first beta release of Drupal 6, also add back E_NOTICE removal for the release.

#175197 by KentByte and webchick: updat CHANGELOG with some important changes we missed to mention here (and wrap lines properly)

  Woot, woot! :)

- Patch #141730 by Earl: allow theming system to use wildcards.  I promised in the issue that this patch would still go in, so here goes.

- Patch #20295 by pyromanfo, webchick, Gurpartap Singh et al: allow forum topics to be custom node types.

revert update status changelog message, 'update' module is not yet in Drupal core, but this change slipped in with http://drupal.org/cvs?commit=71956

  This is a very important patch, but one that is merely an enabler.
  Hopefully we'll see more people submitting "action patches" in the
  near future.

  Thanks for the hard work and persistence, John.  *If* you decide
  to update the Drupal Pro Development book to Drupal 6, make sure
  to add a chapter on actions. ;)

  Let this be the day where we help revolutionize the online society, and the
  way websites and web services interoperate.  Or something.

- Patch #146910 by dww: only allow enabling modules with the same Drupal core compatibility version.

- Patch #115267 by drewish, dopry et al: simplified file uploads code, improved file API, centralized file validation, implemented quotas and fixed file previews.

- Patch #144859 by dww: added optional e-mail notifications when user are approved, blocked, or deleted.

- Patch #141637 by merlinofchaos, gabor, et al: provide a site config form at the end of install to collect data, plus allow profiles to modify and add more.

- Patch #99011 by merlinofchaos: remove sites/default/settings.php and ship with sites/default/default.settings.php.

#127539: progressive operation support, refactoring update.php code to a generic batch API to support runnning operations in multiple HTTP requests
  - update.php is already on the batch API
  - node access rebuilding is in the works
  - automatic locale importing is in the works

 Thanks to Yves Chedemois (yched) for the good code quality, very wide awareness of issues related to batches,
 and the fantastic turnaround times. Hats off.

Add missing items to changelog (clean url tester, sticky table header) and group related items together.
