Added displaced mesh capability to the MultiApp MeshFunction Transfer, and fixed a typo, refs #3372
pressure pulse test p_fu_lumped_22.i tightened convergence criteria and regolded.  Fixes #3368
Tests that allow easy exploration of user objects have been added.

Fixes #3394

These tests are entirely trivial from a test-suite point of view.
They pass if they run.  They fail if the input files cause a crash.

Also a little doco has been added to user.tex that explains the
functionality.
Add kernel and test for thermo-diffusion: #3392.

Enable --error-unused for moose_test
Fixes #3411 .  Corrected uo4.i

Put some error-checking stuff in RichardsMaterial so this won't happen again
and also some LIBMESH_DIM instead of "3".

Also slightly altered RichardsSeffPrimPrimeAux.C to avoid a comparison
between signed and unsigned, which was not the cause of this problem, btw.
