no permanent config with the current image

[smoebody]

I just migrated my blogs running ghost 0.11.x to 1.5 with this image and i am afraid that making the config.production.jsonpermanent is not possible anymore.

One cannot bind a volume to /var/lib/ghost anymore, otherwise ghost refuses to start since essential files and folders are missing. This makes it impossible to apply settings such as mail configuration permanently to the config-file.

@smoebody as has been said in #73 - Ghost 1.0 is able to be configured with environment variables, see the docs.

Closing as a duplicate of #73
