BaseTypes:

- rewrote BaseType::iterate() to be a generator and yield references (requires php 5.5)
- reduced usage of bandaid BaseType::reset()
- removed Util::getIdFieldName() which was even more of a bandaid
- discovered DBSimple::selectPage() and consequently removed $matchQuery as they are now obsoloete

Util:
- added trainerTemplate lists for future use with trainers and trained spells
