Merge pull request #3696 from aeslaughter/soln-uo-3517

SolutionUserObject handles nodal/elemental automagically
Nonzero initial stress components may be specified as functions in TensorMechanicsMaterial

Fixes #3763

I initially wanted to specify the components as AuxVariables, but
i couldn't get it to work because the AuxVars weren't defined at

for me for the present, but if anyone better at moose would like
to change to AuxVariables, i'd be quite happy!
