search: use git approxidate in WWW and "lei q --stdin"

This greatly improves the usability of d:, dt:, and rt: search
prefixes for users already familiar git's "approxidate" feature.

That is, users familiar with the --(since|after|until|before)=
options in git-log(1) and similar commands will be able to use
those dates in the WWW UI.
