JavaScript functions adding behaviours based on IDs or class names where
moved to their own object into behaviour.js and where jQueryized.

This patch adds a simple shell script to easily update the
jQuery/jQuery-UI+theme bundle to the latest available version.

The jQuery-UI CSS theme is now loaded in lib/exe/css.php (before plugin
and template styles - 3rd party authors can override the styles).

This adds a DEPRECATED() JavaScript function. This function will print a
warning to the Browser's debug console if available (Chrome and Firefox
with Firebug extension) when ever it is called.

The DEPRECATED() function was also added to the $() function which
should no longer be used and be replaced with JQuery calls.

Other deprecated functions need to be identified and marked.

This was broken by the JQuery port. This patch makes the page search
work again and also removes the anonymous wrapper function around
ajax_quicksearch again.

The security token here doesn't improve the security as the other
requests that allow you to do the same thing aren't protected and I
don't see why locking or draft creation should be subject of XSRF
attacks.

This disables lock and draft creation for pages the user can't edit. It
additionally adds a security token to the draft creation and deletion
request so - at least for logged in users - drafts can't be created,
modified or deleted so easily anymore.

This works around a new "feature/bug" of Firefox 4.

If no HTML element with the id wiki__text exists, locktimer.init led to a
JavaScript error.

This reverts commit 342e58c8.

The options code had already been fixed. My mistake.

We disabled the media options shortly before the last release because of
an unfixed bug. The disabling was not complete which caused problems
with templates not incorporating the needed CSS.
Since the option dialog hasn't been fixed yet, this patch also disables
the creation of the corresponding HTML to avoid the mentioned template
problems.

I also adjusted the coding style to match our other JS classes

When a <select> tag has the class "quickselect", this script will
automatically submit its parent form when the select value changes.
It also hides the submit button of the form.

This makes it possible for plugin and template authors to overwrite or
extend the quicksearch JavaScript logic.

This patch moves the shortening of namespaces in the quicksearch results
to JavaScript. This makes it independend from used template and will
always try to fill the width of the result pane correctly.

Things missing:

  * Make it work with RTL-languages
  * Check Browser compatibility (only tested in Chrome so far)
