BugID: 1050

A whole bunch of code changes. Most notably:
* All BBSStrategy and all BBSStep classes now inherit from the Command base
  class.
* CommandVisitor is used in quite a number of places to "restore lost type
  information"; i.e. to recover the exact type of a Command.
* CommandQueue now stores and retrieves Commands instead of BBSSteps and
  BBSStrategy.
