Query Branch Updated: Text Entry Bar added

["Gabriel Burt" <gabriel burt gmail com>]

I've committed a text-entry find bar based on some of the ideas from
Thomas's ideas/patch.  It is in the F_SPOT_QUERY branch.

It doesn't do the NOT operator yet, but it does have some nice features like
tag-name completion, automatic closing parenthesis, and tab to move between
terms quickly.

You can see an animated GIF of it in action here:

Thanks,
