This commit first and foremost ports the -tg- atom pooling system, and
removes the old experimental system entirely.
Secondly, this PR modifies the qdel system to use a -tg- lookalike
"destroy hint" system, which means that individual objects can tell qdel
what to do with them beyond taking care of things they need to delete.
This ties into the atom pooling system via a new hint define,
QDEL_HINT_PUTINPOOL, which will place the atom in the pool instead of
deleting it as per standard.
Emitter beams are now fully pooled.
Qdel now has semi-compatibility with all datum types, however it is not
the same as -tg-'s "Queue everything!" system. It simply passes it through
the GC immediately and adds it to the "hard del" lists. This means that
reagents can be qdel'ed, but there is no purpose as of yet, as it is more
or less the same as just deleting them, with the added effect of adding
logs of them being deleted to the garbage collector.
Robot modules weren't handling qdel'd stacks properly, so now they
simply don't get qdel'd. They shouldn't get deleted often enough for
this to hurt performance.
Also, the module slot of a stack will now be deselected when it's used
up, and it will show up immediately when respawned while recharging.
Instead of the AI crew_monitor being a per-AI variable, it was shared by
all AIs, and recreated each time a new AI was created, as part of that
AI's contents. Bots create and delete a new AI every time they transmit,
which means the crew_monitor would be deleted the moment a bot spoke
over the radio, causing it to runtime.
It is now a per-AI variable.
Drop Item will now deselect, and Toggle Throw will now unequip and cycle
to the next module; previously, these hotkeys did nothing for cyborgs.
Also, unequipping a module while the module list is open will now update
it like it should.
This fixes magnetic grippers not being able to mount frames. Also, this
includes an exception for magnetic grippers in the wall code, to prevent
superfluous wall pushes.
