Brittle config file parser

[UpcraftLP]

The config file parser cannot handle the config file existing, but containing invalid data.
This leads to a NumberFormatException here because the returned string is null:

Cardinal-Components-API/cardinal-components-base/src/main/java/org/ladysnake/cca/internal/base/ComponentsInternals.java

Line 59 in d328b40

if (Integer.parseInt(cfg.getProperty("config-version")) < configVersion) {

That exception is not caught and therefore will crash the game.
