Just test stuff... okay if this gets lost... it didn't work anyway.  :/
More 'natural' blink for blank search term--will reuse this later.
Oooops... taxon exemplar-setting code was ... well... bad.  This is actually a pretty significant re-write, but now it's working (and the code it quite a bit clearer to boot).
Adding back some changes (important) to setting exemplars (particularly WRT cache-clearing, but code cleanup, too)
Fixed the specs that I broke on the branch.
