Add option to disable compiling regular expressions

[tetsuo13]

I've experienced IIS processes spinning out of control consuming memory and CPU when using compiled regular expressions in WCF services. This change leaves compiling regular expressions by default but adds the option to not compile them. Must be changed prior to any address parses.

AddressParser addressParser = new AddressParser();
addressParser.CompileRegex = false;
AddressParseResult parserResult = addressParser.ParseAddress(addressString);

Looks good, I'll pull this in soon and update nuget
