Beginning to strip out obsolete Epetra functions from Tpetra branch.
Removed evaluateResponse and evaluateResponseDerivative.  Note that
these are still called in QCAD so the tpetra branch with QCAD will not compile.
I will convert the QCAD responses / model evaluators to tpetra soon so
that it will work.

Note also evaluateResponse is called in Albany_SamplingBasedScalarResponseFunction by
an SG response function; but SG doesn't work yet with Tpetra so it should not be enabled anyway
in the cmake script.
Modifying cmake script to turn off QCAD.
