This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
1. Remove `cooked` becaused only the blurb is used on the client side to
display search results.
2. Remove `ignored` because the result is not used in anyway when
searching for pots.
FEATURE: display category in search results
FEATURE: display topic state (locked/pinned/etc) in search results
UI cleanup for search results, clearing floats and so on.
