Do not hide entities with the BauSystem hullhider

HullHider gets a hideEntities parameter: the fight still hides entities inside
hidden hulls, /hullhider only hides blocks. As the TechHider also dropped
spawn packets at hidden positions, ForPlayer#canAccessEntitySpawn decides
about them now, which the BauTechHider always allows.
