[rules-users] DrlParser problem with soundslike and matches

[Wolfgang Laun]

All the operators that are represented as Keywords must be made known
to the parser;
this includes all the predefined ones. This is done in class EvaluatorRegistry..
See org/drools/base/evaluators/EvaluatorRegistry,java and
org/drools/compiler/PackageBuilderConfiguration.java.
