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.

Conflicts:
	lib/scripts/edit.js
	lib/scripts/locktimer.js

Some whitespace (at end of line) cleanup

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.

Since the password is no longer stored in the session, we need to use the login
cookie instead.

Users with names like foo.bar still didn't receive the mail when user
foo edited the page. Now the two possibilities (space and end of line)
are tested instead of just a word boundary.

This fixes the subscription user regex to really only not to match the
author of the change but to still match users who have that username as
substring in their username.
