This freezes many things that normally happen automatically
in the world, including most ABMs and AISMs, and a few other
custom step logic items like the player "hot potato" logic.
This can be used for "creative mode" purposes to setup a complex
build without it running itself away from you, and for texture
pack authors, to have time to see things that are normally
transient or difficult to observe because of the effects they have
on nearby things or players.
Treat all API mods as a "layer", and use the new
nc_api_all registration to indicate that a mod depends
on the NC API (which ALL NC mods assume they do).
This means that each non-API mod does not need to
worry about which API mods it really needs and which
it does not, nor will they need to be updated for any
internal API restructures.
This is a game, not a modpack, so all mods will be
loaded anyway, and we only care about order. That
means that we don't really need to worry about
having excess dependencies because any mod we
don't actually need will be needed by something that's
loaded anyway. If somebody wants to reuse a
component elsewhere, they're likely to need to do
some work to untangle it anyway, because of the
amount that NodeCore mechanics interact and
interdepend.
This created a ton of dependency inversions, which
necessitated moving a number of API functions up into
higher layers, and restructuring dependency lists for
a number of mods.
BOLO: non-deterministic load errors due to missed
dependencies.
