Ablative coating gives +100% laser *and* particle resist. Particle resistance coating gives only the particle resist. But ablative coating is cheaper and lower-level.

It used to give a lesser resist to particle damage, but with the swap to modern enhancement code that probably got lost along the way. Definitely worth a fix.

In 1.9 Beta 4 ablative only gives +100% to laser and none to particle.
