[Bro] String methods

[Martin Casado]

  I'm doing a bit of string processing and would like to expose the 
BroString::ToUpper(..) to
the script as well as provide a case insensitive string (or r.e.) 
matching method.  Do these
methods currently exist? If not, may I implement them with hopes of 
integrating them into
the main source branch?

 thanks :)
