Rewritten Uzon.lua

Thanks @ninjalulz
can you check this?
there is no need to set new variables at this line and L57 and L73
just use the former way:
player:getPosition():sendMagicEffect(CONST_ME_TELEPORT)
player:teleportTo(Position(1234, 1234, 1), false)
player:getPosition():sendMagicEffect(CONST_ME_TELEPORT)
