Aaron Suen 4d47ab2e75 NC API dependency simplification.
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.
