std.log available for viewing

[Jose Armando Garcia]

By default the module will read the command line arguments looking for
known option. For any option that is missing the default will be used.
The default for each option is described in FilterConfig,
VerboseConfig and LoggerConfig. I.e. the module works without any
explicit initialization by the user. Look at 'share static this()'.
