extends cbpi-dev-config to be a complete set.

cbpi requires empty folders inside the config folder to fully function, and this commit adds them.
There are also some more extensive checks on missing files and folders newly implemented.
As well as checking for restored_config.zip is now done before checking for config.yaml.
On unsuccessfull restore the zip file is renamed instead of deleted.
