Ogres adjustments

Ogres on day or night need to spawn MAXIMUM between 17-20 minutes
Ogres on night need to get a 25% HP reduction, if you’re in a full pvp lobby, they’re dead objectives for a solo player, way too risky.
Add a map wide shout when an ogre spawns/dies

Ty for adding the secondary ogre on night, but we still need some adjustments to make them viable as objectives for solo/duo, they take way too long to kill atm.
