autocomplete behavior

[sleepylemur]

it needs to be visually clear that autocomplete results serve the sole purpose of filling out the search box. ideally autocomplete results would be in a dropdown that is directly attached to the search box, and tabbing/arrow key/clicking through the autocomplete results would affect the contents of the search box.

once enter is hit or search is clicked, then search results should be displayed.
