* done to support intelliJ checkstyle plugin
* some adjustments in the configuration were required due to version changes
* chore(checkstyle): set validateThrows to false (see http://www.javapractices.com/topic/TopicAction.do?Id=171)
* chore(checkstyle): added further valid abbreviations
* chore(checkstyle): getting rid of more checkstyle warnings
* chore(checkstyle): added SuppressWarnings module so checkstyle warnings can be suppressed if necessary
