When the picker button is near the border of the screen, then an opening panel of picker buttons can go over the screen edge. That's not convenient. So we should add a check in a `function pickerToggle()` and shift picker buttons position if needed.

Add the class .bounce to any element to let it bounce slightly for 2
seconds. This is useful to make the user aware of some element. Can be
combined with #scroll__here when a long list auto scrolls to a certain
item.

This adds a subtle animation effect when scrolling to the #scroll__here
behaviour ID. It also adds a 100px offset to make the object not stick
to the browser border.

This now pulls all data from official jQuery sources. Either their CDN
or their github account. Google tends to serve outdated or even broken
files :-(

Unfortunately there's no simple way to get the latest stable jQuery-UI
so for now the version has to be adjusted manually in the script.

The edittable plugin broke uploading in IE8 (and maybe others) because
the Handsontable script adds a function to the Array prototype and the
uploading script did not properly check that.

we now pull jQuery directly from jquery's CDN instead of google because
google serves slightly outdated versions under the /1/ branch

The updated smoothness theme currently breaks compression. Haven't
figured out why, yet.

MSIE 11 tries hard to break any previous working browser detection
even through feature checks. This resolves to browser sniffing (MSIE for
old IE, Trident for IE11+)

Minified jQuery contains a source mapping hint that will result in a 404
in Chrome. I removed the hint for now. A better solution (eg. fixing the
mapping URL) should be found.

Fixes FS#2837

Removed extraneous whitespace to eliminate errors reported by the
Squiz.WhiteSpace.SuperfluousWhitespace sniff.

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.

As reported in https://forum.dokuwiki.org/thread/9988
the previous implementation can not handle the situation of use the
linkwiz more than once. Now you can use in you toolbar plugin
    'type' => 'linkwiz'
to make use of the handy Linkwizard for choosing the wiki pages.
