Adding initial stub for lb init.

In the past, we had lb config for both creating a configuration directory
and updating settings in there. With the rewrite in Python, we're now
changing this finally to the more sane 'init' (create initial 'sample'
configuration directory tree, taking most arguments that lb config did)
and 'config' which will only be a get/set program to work on top of
an already initialized configuration tree.
