Fix passing alpha/beta/omega in Albany::ModelEvaluator for SG/MP

The time integration constants alpha, beta, and omega were only being
extracted from the InArgs in Albany::ModelEvaluator for deterministic
problems, not for SG or MP problems.  This fixes that.
Update transient SG files for SGBratu1D example.

With the previous fix to the Albany::ModelEvaluator, transient SG
appears to now work.  I changed the final time to 5.0 with 25 time
steps, and it now reproduces the solution from the steady-state solve.
And unlike before, this now appears to be robust to the time-step size.
LCM: Changed block identifier from int to std::string to avoid using
deeply embedded Albany_STKDiscretization maps.
Small changes to materials file
Cleaning up the LCM/KfieldSurfaceElement tests

Rather than a single test, this example will encompass

1) Kfield with hex8 - localization & cohesive surface elements
2) Kfield with tet4 - localization & cohesive surface elements
3) Patch recovery with hexes & tets (tet4 & tet10) - only bulk elements
4) Patch recovery on tet4 with barycentric subdivision - only bulk elements
5) Limited testing of Ifpack and ML preconditioners

Right now the barycentric subdivision is bombing. I'm checking in these tests so that we have something to chat about.

Next step: Commit tests for the hex8 and tet4 with cohesive surface elements. These tests have been verified.
Adding sub-directory within LCM/SurfaceElement for testing subdivision

Barycentric sub-division is not working. I'm just checking in a case that current does not work so that we can fix it.

The next step is to have it run as a test.
LCM: Fixed uninitialized variables.
Updating tests for notched Kfield

These tests are attempting to isolate shear bands that are forming under extreme deformations at crack tips.

They should not be there. This exercises only the bulk elements and the balance of linear momentum.
LCM: Fixed typo in Schwarz BC type. Hooked up now. We just need to make
it do something.
LCM: Need discretization in Schwarz BC. Pass it around.
