Make J Integral tests more tolerant of machine differences ref #3633

For these tests, the nonlinear residual won't drop any lower than
about 5e-4, which translates to a relative tolerance of about 1e-8.
The domain integrals are pretty sensitive to small differences in
the solution, so I've had to use pretty loose tolerances to get
this test to pass cross-platform, and it's still been problematic.

I've tried a lot of things to try to get this to converge tighter,
and haven't found anything that makes a difference.

That convergence floor seems to be independent of the load, so I
increased the loading by a factor of 1000, which permits solving
to a much tighter relative tolerance.  I also made these use the
default setting for pc_hypre_boomeramg_strong_threshold.

Mohr Coulomb added - 12 tests added ranging from trivial exception
tests, to somewhat more complicated tests that map out the yield
surface with hardening and smoothing.

I'd really like people to start using this so we make the algorithms
more robust.  I don't think there are any explicit bugs, but this
particular non-linear root-finding problem is numerically more
challenging than the other plasticity models, so for particular
combinations of tolerances, etc, the algorithm could fail to converge.
It would be nice to know what those combinations are so we can build
a better algorithm!

Fixes #3627

Make J Integral tests more tolerant of machine differences
Add option to action to output variable values along crack ref #3671

This adds the parameter 'output_variable', which the user can specify
to create PostProcessors that output the values of variables along
the crack.  The naming scheme of those PostProcessors matches that of
those used to calculate domain integrals.  This will allow comparing
toughness to stress intensity at locations along the crack.
