Changed the condition on LimboProvider.canRespawnHere() so that players can respawn in Limbo even if LimboEnabled is false. LimboEnabled only controls whether players are sent to Limbo when they die in a pocket. It does not prevent players from ending up in Limbo because of Monoliths. If Hardcore Limbo is enabled, it stands to reason that people should be respawning in Limbo anyway.
