documentation on configuration options

[cKlee]

Please provide an extended documentation of the options in config.json. The examples under /config are not sufficient. It's really hard to find config options within the scripts and figure out what effects they have. E.g. "routers", "assetsPath", "blankNodePrefix" etc. A full list and a hint on the effect would be fine.

Thanks in advance!

Just add the missing fields with their default value to config/config-defaults.json and issue a pull request!
