  Issue 1086:  Batch compilation support:
  * $MSVC_BATCH to control Visual C/C++ batch compilation.
  * New $CHANGED_SOURCES, $CHANGED_TARGETS, $UNCHANGED_SOURCES and
    $UNCHANGED_TARGETS construction variables.
  * New Action(batch_key=, targets=) keyword arguments.

  Use UniqueList objects to collect the all_children(), all_prerequisites()
  and all_sources() lists instead of calling uniquer_hashables() by hand.
