Split up default "core" config parsing into helper routine

It makes the code a bit easier to read, and in theory a bit faster too
(no need to compare all the different "core.*" strings against non-core
config options).

The config system really should get something of a complete overhaul,
but in the absense of that, this at least improves on it a tiny bit.
