[FIX] Search view's drawer closing unexpectedly when using the date widget

jquery-ui's date picker (at least in currently used version) lets
*some* (but not all) clicks go through. The date picker dialog is
added directly to the page body so capturing clicks in a parent widget
doesn't work, and these "stray" bubbling clicks will trigger the
global bus's "click" event.

Add a capturing (and stopPropagation-ing) of these clicks in our
wrapper to jquery-ui's datepicker to avoid the issue.
