Happy New Year

Set email User-Agents.

Remove references to unimplemented and unused info.php/debug.php/INFO/DEBUG modes

Fix & simply the search.  Searching now returns results for an exact match,
title matches, and page text matches, all on one page.  Still need work on
a paging feature for the results.

Use new MIME_Mail class.

Don't use the same name for session vars as for global vars.

Initial CAPTCHA support.

Revert.

brace style goes back and forth, back and forth, back and forth ...

[cjh] Encode notification emails correctly (tasin@fhm.edu, Bug #3153).

That didn't work.

Add placeholders to make the page names with access keys translateable.

Add access keys to menu items.

We don't get anything out of asking for a reference here, since it's
not a singleton, and it apparently throws errors sometime.
Bug: 2815

"@access public" is redundant.

Fix support for page names with slashes.

[cjh] Add a config option to toggle use of pretty URLS with mod_rewrite
(Bug #1878).

Use Text_Wiki's wiki word regexp.

Typo.

Bug: 1882

[cjh] Send email on MergeOrRename (Bug #916).

Also move a bunch of work into Wicked::mail() and rely on it to abort
if notifications aren't enabled; cleans up the places where it's
called.

New menu.

Registry::getParam() -> Registry::get().

Apps no longer need to call Help::javascript() - and indeed they shouldn't,
since it no longer exists.

* Replace page-specific wicked blocks with a generic wicked page block that
can display any page.

* Add ability to attach files to wiki pages.

* Introduce WICKED_REGEXP_WIKIWORD so we don't have WikiWord regexps all over
the place.
* BackLinks will now match references at the start or end of the wiki page,
and if the page name isn't a valid WikiWord, will now require match to be
in ((...)) form.

- Remove a boatload of unused constants and preferences.
- Add WICKED_MODE_CONTENT for fetching just page content.

A bit more error checking in Wicked::mail(), avoid undefined index errors,
and better fallback logic if the guest_address isn't set.

Add configuration option for email address to bes used for guest commits.

No more HORDE_LIBS.

Ditch $conf['wicked']['allow_guests'] in favor of respecting page permissions.
If a page does not exist, permission to create it will be controlled by the base
'wicked' permission, and if that doesn't exist, then authenticated users
will be permitted, and guests will not.

move Menu.php to a framework package.

Use Identity::singleton().

Show notifications only from the requested message stack.

Identity moved to framework.

Move mail code to Wicked::

Wrap lines.

Some default pages (most not used yet), and a bunch of cleanup to try and get
this closer to working order.

- Wicke -> Wicked, should be globally.

- Cleanup, some modernization.

Initial import of Wicked, original code written by Tyler Colbert
<tyler-hordeml@colberts.us>. The initial name was "wicke", so a lot of
d's need to be added in various places, but this should be a complete,
otherwise functional start on a Horde Wiki.
