Eggs No Longer Have Melee Resistance (#4555)

# About the pull request

Eggs no longer have magical resistance to certain kinds of melee damage.

# Explain why it's good for the game

The old system means certain melee weapons are utterly ineffective
against eggs, wheras others are lethally effective (a breaching hammer
or knife taking forever to kill one egg, but a machete or axe taking 2
swings).

I'd also argue a giant blunt force attack would be more effective
against an egg than a edged blade.
