release v0.2.10

This release works with the current dp/DB v0.2.10 and includes recent changes of model_draft.
Additionally, it provides the first version of a config creator and DB connection provider #24.

With this release u can simply use ego.io for your DB connections, e.g.:

from egoio.tools.db import connection

conn = connection(section=...)
Session = sessionmaker(bind=conn)
session = Session()

If the DB config file ~/.egoio/config.ini does not exist, it will ask you to create it with provided host, user etc.
