Comment 3 for bug 1548993

OK. I have added a commit to the branch to remember the state of the Show More/Fewer Details button across searches. I made this a separate commit in case the consensus ends up being that we want to stick with the original behavior of it clearing when starting a new search.

I've tried it out on concerto and it pretty much works. I noticed that the state does get cleared if you hit 'Clear Form' on advanced search. I'll leave that as desired behavior for now. If someone else wants to try and change that, feel free.
