Checked off tasks already covered by prior work.

For some features, support won't be completely added when this is done, b/c I'll need to go through each race, class ability, etc. to see what interactions I've missed.

[tyoung-99]

Need to update dynamic HP/AC to search list of modifiers, like hit/damage do, instead of depending on links to modifiers.

Features listed above are all implemented, so this will be closed, but new dynamic features will likely be thought of in the future. Those can be handled in their own issues, if not during related features' creation.
