Check json schema for config options

[tilmanschweitzer]

'file-name' rule has no option schema definition. Check if other schemas are missing as well.

some of them do not have Schema def, because it impossible, I think, to define a parameter that can be a string OR a regexp (like controller-name).

Ok, thanks for the information.

This is now better validated, because of #346. It is no longer possible to accept configs which don't exist in the schema. I think this issue can be closed now.

Closing this, as I think all schemas are covered now.
