Update 1.10.4.0

New Shadow Mob: Epion - Giant Death Bats!

New items Added: Blood Leach Charge and Scepter - A life draining
projectile!

New Spawn Type Added: Lunar - Used to spawn Epions during the full moon
at night!

Event Change: Shadow Mobs no longer spawns Phantoms, instead it spawns
Epions in their place with the Grue. Phantoms will be added to a new
event soon.

Major Bug Fix: Mobs spawned by none-event spawners should now despawn,
mobs that have already been spawned with this bug will still not despawn
however as their persistence is saved, they can been removed using
peaceful difficulty, or killed off if possible though.

Bug Fix: Some spawners weren't ignoring the dimension when they should
have been.
