Don't damage armor when drowning, eating or starving.

Fixes stujones11#119.

Note for a hunger mod to properly support this they must give the reason when changing the player's health. The changes for the hunger_ng mod were merged, but I haven't looked at any other hunger mods.

Instead of checking the specific reason, I am checking only whether reason.hunger is nil or not. I think armor should not be damaged from eating foods or starving regardless of the reason?

Looks good 👍 thanks.

I'm using the stamina mod mostly and it doesn't set the reason parameter (yet):

This does provide a backward compatible way to improve things like that..
