Autocomplete update


Implemented a searchAutocomplete widget on top of autocomplete:
http://jquery-ui.googlecode.com/svn/branches/dev/tests/visual/autocomplete/select.html
Currently the button displays all results, giving focus to the input
for keyboard control. When entering a value, the list is displayed,
too, but not filtered; instead matches are highlighted in the results.
Pleae review and comment this as well as the default visual test:
http://localhost:81/jquery-ui-dev/tests/visual/autocomplete/default.html
I hope FG can improve the Theme for both tests, eg. matching the input
to the button height.
