use flashmessenger directly from $this->_helper, use namespace, cleanup plugin/view.php
adjusted validators/collectionpresentationtypes, but probably obsolete.
question management (work in progress):
*adjust (edit) form to use (without use of database/model)
*add form-wizard logic (redirect to correct tab)
*cleaned controller: editAction (but for now save is disabled)
*moved save action from form class to model class
*model: start with toArray class
*start of model_answerDomain class
