Removes the `module.ConfigFile` function. We do not need to
dictate what the file name for any config data is for
a given module. The `module.DataDir` directory path is
more than enough. Leave it up to each module to decide
how and where to store their data.

This changes the CreateDefaultConfig behaviour through the
`-conf` command line option. Instead of checking for a
specific file name, the code now checks for the data directory
presence to determine if config data should be regenerated.
