We now have reports with a growing number of available filters and conditions to be added - the current select element for choosing which to add to reports is a bit unwieldy (especially when you know which you want to add, but have to scroll to find it)

Improve that by enhancing the select elements with the existing autocomplete module - this will provide existing functionality, with the addition of search support (so users can quickly find the element they're looking for)

Provide implementation of the same here, then mikelmartíncorrales will add his artistic design to it to make it look cool
