Minor clean up and doc fixes

* Remove commented out arguments.
* Fix broken reference to OO#getHash (doesn't get linked, class
  is indexed as OO not oo).
* Fix broken reference to ve.dm.Converter#getDomSubtreeFromData.
* Consistently index abstract methods as @abstract.
* Fix broken list (list needs to be a new block, will be parsed
  as continuation of paragraph otherwise).
* Fix broken @extends (doesn't take value in curly braces, was
  being parsed as literal text part of the class description).
