Add ability to set html autocomplete property to "off" for exposed filters

This can currently be easily achieved using jQuery:

jQuery('.views-exposed-form input[type=text]').attr('autocomplete', 'off');

It would be nicer to have this option generated by php code instead:

<input type="text" autocomplete="off" ...

Small annoyance for users trying to filter a list that uses AJAX; a popup comes up with previously entered items but the user is likely to only enter a few characters. Just a checkbox or a an input field to enter additional properties would solve this nicely and easily.
