Don't send back URLs in survey questions

As discussed in Issue #28, we were sending back URLs in the survey question text. This removes URLs from survey questions by allowing you to set a nickname (short name) for each question. The short name is sent back instead of the actual question text, if the question text has a URL.
Nit: The indentation of the closing parenthesis looks a bit...odd? I feel there should be aligned to the left one level (that is, delete two spaces).
