Neil McErlean 6fd9628330 ALF-8498. Reimplemented the Comment Count Rollups to take pre-Swift, commented nodes into account. Also added a trigger for a recalculation.
Major refactoring of existing onCreateNode/beforeDeleteNode(fm:post) behaviours. They now distinguish between
    1. increment/decrement of previously rolled-up commentCounts
    2. full recalculation of comment count for nodes that have no previous rollup (which would include nodes from pre-Swift repos).
  Added a new registered behaviour: onUpdateProperties(fm:commentsRollup) in order to detect fm:commentCount being set to a "trigger value".
    If this property is set to a negative number, then a full recalculation of the commentCount for that node will be performed.
  New test cases for preSwift content & the recount trigger.
  Added a skeleton (placeholder) CommentService to hold some comment-related methods I needed.
