Updates the way that the system config validates the resource
config to ensure that its not possible to set config values
that break the system. It is possible to set config values
that would burn too much gas, rendering the system unusable.
Every error cannot be caught, so try to catch the most possible.
Altering the default resource config is not recommended, but it
is possible.

This also adds fuzz tests that cover the problem, if the change
in the require statement in the system config contract is reverted,
then the fuzz tests catch the `UNDEFINED` error quite quickly.
