Cleanup Plus Search

Another batch of ongoing housekeeping. I added a search field up and to your right, which just outsources the problem to Google. Eventually there’ll be something with an ongoing look coming out of this. Also I fixed a long-standing bug in the date display, which convinced me the whole date-hierarchy subsystem was basically broken so I re-did it, check it out. Quite likely I broke something, if so let me know, my email address is on the front page of a Google search for my name. Also, IE6 was refusing to render ' properly for reasons I couldn’t figure out, so I skated around that.
