Wildcard search improvements

[davidteal]

Hi there.

As far as I can see, I don't think wildcard searches work on urls with a query string as the preg_match tries to use the ? as part of the expression. I fixed this by escaping ? characters in the str_replace.

Also, using * as the start of the redirect doesn't work due to using strpos($record['uri'], "*") which returns 0 and therefore doesn't pass the if statement. Should use strpos($record['uri'], "*") !== false

Happy to submit PR
