changes for JQuery UI 1.11.0

Most of these changes are automatically generated from the rake task

I have tested it, it works.

Though I think a design decision needs to be made as the upstream changes in JQuery remove file prefixes, which were probably useful within statements like "//= require jquery.ui.datepicker" this change makes those "//= require datepicker".  Retrospectively though, I wonder if it wouldn't be better to manipulate things to maintain the existing behaviour.
