Fixes FS#2837

Fix violations for the following sniff
DokuWiki.Functions.OpeningFunctionBrace

Also removed an extraneous semicolon.

When debugging is enabled (allowdebug enabled) JS errors are now catched
for each non-core JS file and logged with the additional information
from which file they came. This should make it easier to find out which
plugin is the cause for broken JS code. The feature isn't enabled by
default as defining functions inside try-clauses isn't allowed in strict
mode and causes a warning at least in Firefox.

this disables the JavaScript compatibility layer which let pre-jQuery
migration plugins run with their old code.

This will break plugins using outdated JavaScript. These plugins have to
be updated according to https://www.dokuwiki.org/devel:jqueryfaq

As a courtesy to users, the compatibility.js is not deleted, yet.
Undoing this single patch can be used as a temporary workaround.

this will be removed soon again. plugins using jQuery should make sure
they are compatible to jQuery 1.9

* jQuery 1.9.0
* jQuery-UI v1.9.2
* jQuery.fn.live > jQuery.fn.on
* jQuery.fn.browser replacement (jquery.mb.browser.js)

This simplifies a while loop in the js_compress() code. The
functionality of the new code is completely identical to the old code
but it uses less comparisons and according to FS#2593 it is thus a lot
faster.

See

for info on them.

This removes the cachekey parameter again and instead follows
@michitux's suggestion to trigger an event for the cache usage

This reverts commit ba6c070e.
This reverts commit 92351008.

jquerized

Make it faster, prettier, less wrong, add UI effects, use jQuery UI Dialog,
Abstract tree view stuff away into jQuery.dw_tree

There are probably more functions that should go in here

  * Increase HTTP cache time since the resources are timestamped on request
    anyway
  * Check userscript.js only once for JS cache validation
  * Use cache class

  * Move file to qsearch.js
  * Rename object to dw_qsearch
  * Remove unnecessary usage of Delay
  * Use $ prefix for jQuery objects
  * Fix result list hiding on click
  * Fix namespace shorting

  * Removed "use strict" statement, since it does not work with our script file
    joining (the statement has to be the first in a file or function)
  * Make index a global object again to allow overriding and enhancing
  * Use prefix dw_ for index object
  * Reintroduce index.treeattach
  * Support deprecated index.toggle calling convention
  * Add $ prefix for jQuery variables
  * Use slide animation for freshly loaded sublists as well
  * Fix various errors

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

This fixes a problem with running the minified jQuery through the
compressor.

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 avoids problems when the files are concatenated later.

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