I recently finished Enderal and thought the food system is really nice.
You actually have to prepare a lot before venturing out because the passive regeneration comes from the food.

So I spent some time implementing the same concept on top of CACO,
it also tries to modify a few things I do not like about CACO.
It does a few things.

Features:
1.Disable passive regeneration altogether(in and out of combat).
2.Replace the long-lasting HealRate effect in CACO with the out-of-combat passive regeneration.
   Before it only increases the passive regen by 2 to 20 percent which is useless. I hand edited the values for all the foods using that effect.
3.Potions with healRate multiplier now has 1 more effect, gaining 60-100% combat healing rate, meaning you will have 60% to 100% healing as if you 
   are not in combat as long as the effect is there. Without this change those potions actually are useless.
4.Modified the fortify magicka/stamina regeneration and fortifyWeight magnitude used by all foods. Before most of those effects are 2%-3%, now it is            rescaled to 6%-9%(there are still some op food +15-20%). I understand food effect should be subtle, but come on 2%? this is regeneration, even 20% is not    that op.

Notice:
the 100% healing rate is 1% of health per second.

Requirements:
CACO

Notice:
version 0.1 and 0.2 do not support existing games, please use 0.3 and up.

Let me know if you guys encounter any bug/issue. I might add more features to this mod but it is up to you guys' feedback.
