* Added white-box TheoryEngine test that tests the rewriter

* Added regression documentation to test/regress/README

* Added ability to print types of vars in expr printouts
  with iomanipulator Node::printtypes(true)... for example,
    Warning() << Node::printtypes(true) << n << std::endl;

* Types-printing can be specified on the command line with
  --print-expr-types

* Improved type handling facilities and theoryOf().
  For now, SORT_TYPE moved from builtin theory to UF theory
  to match old behavior.

* Additional gdb debug functionality.  Now we have:

    debugPrintNode(Node)            debugPrintRawNode(Node)
    debugPrintTNode(TNode)          debugPrintRawTNode(TNode)
    debugPrintTypeNode(TypeNode)    debugPrintRawTypeNode(TypeNode)
    debugPrintNodeValue(NodeValue*) debugPrintRawNodeValue(NodeValue*)

  they all print a {Node,TNode,NodeValue*} from the debugger.
  The "Raw" versions print a very low-level AST-like form.
  The regular versions do the same as operator<<, but force
  full printing on (no depth-limiting).

* Other trivial fixes
