chore(.gitignore): add standard node gitignore
fix(package): add dependency

Current defaults cannot be run, so adding dependencies for:

* toobusy
* mwc_plugin_example: there's still a problem with DI, app won't run without direct dependency on the plugins
* example config changed to use default redis port

Breaking changes: changes in default configuration (redis port and mongodb database names)
chore(gruntfile): add jshint and vows
chore(readme): add information about grunt
