core.configmanager: Add ways to read config values from files Inspired by something MattJ said Allows retrieving config values from files which are expected to be relative to the config directory, extending on the ENV_ method of retrieving config values from outside the config file. - FileLine retrieves the first line, stripping any trailing newline - FileContents reads the whole file - FileLines reads lines into an array
