Update changelog through 0.13-a0-1380-g03ef21a.

Probably I've missed some significant things; if so, go add them in!
Some other important highlights for the changelog.
Added parentheses to gargoyle petrify-stat-loss.

Now their stat loss is based off of maximum damage reduced in a single
hit, instead of the unreduced size of the largest single hit.
There were missing parentheses resulting in no-op arithmetic.
Don't recommend gargoyle necromancers (snow)
Tweak Gargoyle Aptitudes
Tweak Self-Petrify

Decrease movement speed.
Give fast healing.
Describe self-petrification
Fix the errors of 323b9f5af

It would be much better to take the mana first in all cases, but with the
way aborting spells currently works, it would take some refactoring.
