added excludeInternalGroupIds configuration parameter that allows the exclusion of groupIds of internal projects. This is to speed up analysis as internal projects have no public vulnerabilites nor a sonatype listing but do frequently have names that collide with other libraries. The parameter can have multiple values, e.g. <excludeInternalGroupIds><groupId>nl.someinteral.project</groupId><groupId>org.another.one</groupId></excludeInternalGroupIds>
