Please publish latest GalSim and tmv packages

I've updated, tagged, and built (via buildbot) new versions of two packages:

• tmv 0.72.lsst1
• GalSim 1.2.lsst2
  Eups tag b748 includes both of these.

Please publish eups distrib packages of these (they're dependencies of meas_extensions_shapeHSM, which I've just resurrected from bitrot, and would now like to include with the rest of the stack).

Alternatively, feel free to reassign to me if you also give me lsstsw privileges.
