New GetCreatureSpawnId and SetCorpseDelay functions

- Implemented new function to get the creatures spawn ID:
	- Example:
	- In Lua, write "creature:GetCreatureSpawnId()"

- Implemented new function to set a creatures corpse delay:
	- Example:
	- In Lua, write "creature:SetCorpseDelay(5000)"

Thanks Sylian!
