This is part 1 of a project to, eventually, bring the render planes
system from /tg/ and bay into Aurora. This is a prerequisite and blocker
for many things the development team and community want to have, and
this was long overdue.
Many objects have been re-assigned layers, which are now thoroughly
defined. Maps have had their custom layer defines purged, as we should
be moving away from this in favor of saner definitions in the base
items.
This should be a test-merge due to the sheer amount of layers changed,
which will very likely create issues that I cannot possibly discover and
debug in a reasonable amount of time myself.

Ports Baystation12/Baystation12#19992 and Baystation12/Baystation12#27266.
Added a personal shield device to the traitor tools uplink.
Added a radiant shielding aura spell to Battlemage and Cleric.
Added an exosuit shield drone to the mechfab.
This works, but I'm not entirely happy with the sprites. The personal shield has no on-mob shimmer, it uses a mindbatterer grenade as an icon sprite. The wizard radiant spell uses a pretty big and janky sprite as an on-mob, and the exosuit's shield sprite doesn't follow the dir the mech faces, but that one I can maybe fix on my own. If anyone knows about that last one, lemme know, Bay had code for it that we do not.
