Added B option to RewriteRule

If the query string includes a properly escaped # (%23) then apache won't properly deal with that during the RewriteRule, so you have to add the B option, per http://stackoverflow.com/questions/9384796/apache-rewriting-eats-one-level-of-escaping-23 and http://httpd.apache.org/docs/current/rewrite/flags.html#flag_b . Without this option, in the url: url.com/%23none+of+this+shows+up.
