Update JQuery & JQueryUI

[sgiehl]

New versions of jQuery & jQueryUI have been released.

We should update to the latest
jQuery 1.11.0
jQueryUI 1.10.4

Maybe some plugins like jQPlot could be update, too

just for discussion:
update to latest of v1.x or directly to 2.x?

Since roughly all of piwik users are advanced web-users,
maybe the main drawback for not using 2.x the incompatibility to older browser (like IE before 9.0) will not be a problem at all in our case,
because every even semi-advanced web-user updates his browser regularly...

Using 2.0 one could only add the modules you really need - which should make everything a little smaller and faster..

No. We still need to use 1.x. There are many companies using piwik and some of them might still use IE < 9 - and in big companies it's not always such easy to get an update...

Piwik officially supports IE 8 for some more time. We will drop support for IE8 in this ticket: #4620
