added all the necessary changes to make nimonik deployment work for errbit to example files

This way they are under git for easy retrieval.

NOTE 1: the config.yml file contains only deployment-related stuff; there is another config.yml in nimonik_ops that adds production-related stuff like email integration.
NOTE 2: database.yml is only production-related, so it resides in nimonik_ops.
NOTE 3: deploy.rb contains some additions/changes like depoyment target host and port + errbit:seed task to initialize the admin user.
