Simplified HistoryAssembler and HistoryBuilder API (breaking change)

A history request is now used to communicate all the history assembly instructions.

* ShowAllActivities = true - will get all activity entries
* HistoryItemLimit - now uses MaximumRows on the generic.
Restored HistoryBuilder support for multiple ids.

Case retrieval of subcase history now does only one history request rather than 1 per subcase.
