Small Wormwood QoL for summons

[HowlVoid]

Pretty simple: 

When Wormwood goes to "craft" a summon and he already has the max or has no more items to craft one, he can sacrifice hp to divide the timer of a summon among all available summons (up to cap). 

Example:

Wormwood with two saladmanders shares hp to give each salamander +1 day.

Wormwood with 1 carrat, no other carrots, sacrifices hp and gives that carrat +3 days.

Wormwood with 2 bulbous lightbugs, sacrifices hp to give each one 10 minutes.

All this does is allow Wormwood to maintain his pets without having to repeat the summoning animation every 2-3 days, middle fight, or when you want to travel across the world only to see one died a while ago.
