An almost complete rewrite of all RE patterns. Supports a more complete set of possible characters and also special characters referenced mentioned in http://jakarta.apache.org/lucene/docs/queryparsersyntax.html. Supports full query parser syntax except for AND NOT OR, but warns user of possible errors for these queries. Added alertUser option to disable window.alert boxes.
