Created seeds to initialize database with dummy tasks.
Introduce config module to handle configurations per environment. See https://github.com/lorenwest/node-config
Updated README.md to reflect changes.
Added orm module to abstract Sequelize usage to some degree. ORM module
handles the configuration and instantiation of Sequelize. Models are
defined and instantiated from models/*
Tested only against SQLite.
Faily new to nodejs so I probably messed up with something.
