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

#172773 by numerous contributors: Make the actions interface usable by mere mortals (including rename of actions.module to trigger, but keeping the actions themselfs).

Complete previous history of actions module:
 - #148410 by jvandyk: added rewrite of the actions module!
 - #155986 by Uwe: fixed typos.
 - #155828 by Eaton, pwolanin and jvandyk: let actions live even if actions.module is not turned on

#159527 by chx, webernet and pwolanin: fix system admin menus if admin menu was moved from the default location

#111127 by chx: cache node_load(), so heavy operations loading data from external sources and only invoked once (note that you should do everything dynamic in the view op, not the load op)

#166593 by hswong3i: move literal values out of some core queries to support cross-database compatibility (ie. better SQL parsing and altering options)

#160168 by kkaefer and pwolanin: restore lost Drupal 5 functionality of being able to set primary and secondary links differently

#161136 by hass: the previously aggressive caching incompatible hook_init parts were broken out to hook_boot, so this should be reflected in the help text and check

- Patch #163191 by hswong3i: removed db_num_rows() for compatibility with Oracle and DB2.  Also a performance improvement.

#166491 by pwolanin: default theme settings page should display default theme settings, not the theme list

- Patch #148346 by Steef and drewish: split image.inc into image.inc and image.gd.inc and improved the documentation.

  This is a small form API extension (doesn't break existing code) that
  facilitates the Drupal 6 upgrade of the Views module.  A good example
  of why it can be beneficial to start upgrading your modules early on in
  the code freeze. ;)

#156910 by asimmonds: fix code indentation problems introduced with new code in this development cycle; only whitespace changes

- Patch #154398 by quicksketch et al: add dynamic AHAH submission properties to Forms API.  This patch was ready for a long time and is somewhat of a usability improvement (enabler).

- Patch #33334 by ChrisKennedy and wulf: admin/modules links to 'throttle configuration page' even when it is disabled.

#141725 by Crell and dvessel: allow themes to define multiple CSS and JS files in their .info files, which can be clearly overriden

  unanimously agreed to rollback the deletion API.  We all support the
  features this patch added, yet not its actual design and implementation.
  After some talk, we decided that it would be better for Drupal -- in the
  long term -- not to go with a solution that isn't 100%. We also recognize
  that in the short term, this patch would have been useful addition. So
  let's figure out how we can implement this properly in D7.

#154064 by pwolanin: get hook_help() up to speed to menu changes, allowing router path based lookups, and also full path argument lookup with a passed argument array

  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. ;)

#154949 by Crell and dww: let modules and themes specify a minimum required PHP version, under which they will not be possible to be turned on

#118026 by kkaefer with fixes from myself: JavaScript translation support and script.js as a default theme JS file to use, if found
