Feature: Search for unclear text

[benwbrum]

Transcribers often indicate unclear readings by the standard use of square-braces and question marks, like [this?] or this[?]. As these are control characters for MySQL's full-text search, the normal search can't find them. Wouldn't it be cool if we could mine these to present a list of pages that need review, akin to the top-ten lists? At minimum, we need to be able to search for such marks.

Looking through the Klauber site, some transcribers are marking unclear readings with ???. This also needs support.
