Changed my mind on the sign convention again since I rederived
everything using this convention.
Move this outside of the loop since we reuse it.

Ack, forgot to remove this part.
Move PSPG term into element_constraint.
Sign convention correction.
Move PSPG term in Boussinesq adjoint stabilization into
element_constraint.
We really want incompressible Navier-Stokes name there.
Use Q1Q1 since the element_constraint fix got the PSPG term working.
Updating convection_cell input file to use fixed/updated stabilization
Add initial condition on velocity to force instability
Derp, not sure how these snuck in.
