Scholar.Items.search(text) -- (extremely) simple fulltext search on all fields -- returns an array of ids of matching items

The real search function will be considerably more advanced/flexible, but this should work as a placeholder for the moment. Probably quick enough for FAYT, at least with a ~0.5 second delay to avoid unnecessary calls while people are typing (which is probably a good idea anyway). This search doesn't use indexes at all, so if more speed is needed, one option would be to maintain a manual FULLTEXT-type index (using triggers, ideally) that could be quickly searched, but we'd lose intra-word filtering, which people would probably expect...
