Configuration verifier

[Rainer Hilmer]

Create a class that verifies all config settings except for Booleans. For instance, a JobDelayMin value which is greater than JobDelayMax should not be accepted, or negative values should not be accepted. I think the mod should shut down with an error message about the misconfiguration and what value in specific was wrong.
