Merge pull request #8 from CESM-Development/billsacks/zero_dynbal_fluxes

When we have daily rather than annual glacier dynamics (as we do in this
testmod, due to having test_coupling in user_nl_cism), CLM applies the
dynbal adjustments in a single time step rather than spreading them
throughout the year. This can cause sensible heat fluxes of thousands of
W m-2, which causes CAM's PBL scheme to blow up. So force these fluxes
to zero for this testmod; this breaks water and energy conservation in
CLM, but should allow the test to pass.

This depends on clm4_5_15_r235
