Bulk reader import bug fix + new API snippet variable

Two small changes for today:

In the reader bulk importer, we discovered that if you had the same reader name twice, but one of the rows had trailing blank spaces, the bulk reader importer wouldn't identify them as duplicates. It would strip the trailing blank spaces, though, so it created duplicate reader accounts in this situation. We updated the importer so that it trims all blank spaces first before evaluating for duplicates.

If you're using API calls in snippets, we've added a new variable you can use in your API calls: %cur_search_term%. It will pull in the "phrase" parameter in the URL. This might be useful for searching a specific category, searching another knowledge base and displaying the results, or building a custom search.

Also, since you took the time to read this: I can't give you much as a reward. But have you ever wondered how owls can turn their heads so far around? So did I, and it turns out it's a combination of oversized arteries with detour connections. #themoreyouknow
