Remove jQuery UI for search

[jessedobbelaere]

• Remove jQuery UI in frontend.
• Move the search functionality to the search module instead of the frontend.js file.
• When the search module/widget is used on a page, typeahead.js & bloodhound is loaded and used to autocomplete the search results.

Warning: jQuery UI is used in the frontend for search autocomplete and datepicker fallback (from html5 datepickers). So there should be a solution for datepickers. Or just remove the jquery ui datepicker fallback from the frontend.js and leave only the html5 datepicker? Webdevelopers using forkcms should use pickadate.js or similar when creating datepickers.

Preview with typeahead.js:

No real changes noticeable. Wrote some css that's similar to the previous forkcms search autocomplete.

Resolves #1303

Can't you use a minified version of typeahead.bundle.js?

I'd also add a if ($.isFunction($.fn.datepicker)) around the datepicker code in the frontend.
This way, frontenders can still add jquery ui (or another library if they want) on pages containing a datepicker.

@WouterSioen I added the minified version and datepicker check :-)
