Passed uniform refine level when creating mesh from another
Added ability to output materials via the Output objects
(refs #3538)
Added testing for material property output via Output objects
(closes #3538)
Make spherical_shell tests more robust ref #3633

These tests had very small loads applied, which resulted in tiny
displacements, so they couldn't converge to very tight relative
tolerances.  Multiplied the load by 1000 and tightened the tolerance.
Also removed the explicit setting of pc_hypre_boomeramg_strong_threshold.

Make spherical_shell tests more robust
Comments addressed (refs #3538)
Merge pull request #3695 from aeslaughter/material-3538

Allow automatic material property output from Output objects
Robustify hoop_stress test closes #3633

Converge tighter, loosen up stress tolerances a bit, use inexact Newton
to speed it up a bit, remove setting of pc_hypre_boomeramg_strong_threshold.
