a bit of web ui tuning.

fixes for initdb issues (thanks, jhutz)

minor cleanups to ACE.pm

A couple of minor fixes on non-keywords things, but mostly this was an
edit of the keywords code to:
	1. make the admin UI work more like the rest of the admin ui
	(still need to do "global" keyword selections)

	2. bring the coding style of the keywords stuff more into line
	with the rest of the codebase

	3. flesh out the helper methods in the keywords modules.

a bunch of tab-related UI cleanup. the start of tabs that reflect the current page.

added the ability to configure queue watchers from the web ui

Lots of stuff should be much cleaner now.
