Fixed temperature

Found a place in the code that is not setting the correct ambient temperature, which in turn changes the wind speed. So after rerunning the Mach 3.6 shock (corresponding to 6.7 km/s) last night on stampede, here's what I found:

The velocity has the particle velocity subtracted. The Mach 1.5 shock can now get star formation too, as expected. Movies tomorrow.

The compressed cloud exhibits a pancake shape. The star is formed at the center of the "pancake". The edge area of the "pancake" is constantly getting shredded by the wind. Material from outside the "pancake" is raining down into the "pancake", but central region of the "pancake" obtained an angular momentum, with the rotation axis aligned with the shock propagation direction. The rotational velocity V_phi is actually much greater than the infall velocity V_r.
