Merge pull request #55 in G/fastr from ~STEPAN.SINDELAR_ORACLE.COM/fastr:GR-131-remove-rfactor to master

* commit 'd66555f1':
  Remove remaining RFactor references.
  Remove creation of RFactor, fix failing tests
  supply proper TypeSystemReference in AsVectorInternal
  proper internal generic dispatch in as.vector
  RAttributable has default method getAttr

Plus few new tests. BinaryBooleanNode: not the most optimal code for factors,
but factor specialization should be removed and dispatched to their R code.

This commit removes the creation of RFactor, but not the class itself yet,
and fixes all the failing tests. However, not all factors references are
removed yet. Note: there is one failing test due to issues in do.call
implementation.
