Update heatshield part.cfg

Changed thermalMassModifier to 1.0 (the old value of 0.001 causes weird temperature values (4) or excessive temperature gains, or both. (probably alternating between very hot and very cold. Much ablation even though temp = 4)

Other changes made here result in very little ablation but are in keeping with stock behavior of low shield ablation rates.

Let me know if any questions!
