* Rename SMT parts (printer, parser) to SMT1

* Change --lang smt to mean SMT-LIBv2
* --lang smt1 now means SMT-LIBv1

* SMT-LIBv2 parser now gives helpful error if input looks like v1
* SMT-LIBv1 parser now gives helpful error if input looks like v2
* CVC presentation language parser now gives helpful error if input
  looks like either SMT-LIB v1 or v2

* Other associated changes
