feat(orderedList): make orderedList a non-singleton so tours have their own steps
feat(cookies): replace jquery cookie with angular-cookie
feat(tour): heavily refactored cookie management, tour emits events now

cookie management is now mostly its own service, which listens for events emitted by the tour to keep cookies in sync
refactor(tour): adding some comments and more clean up
refactor(tour): more cleanup
docs(readme): updated configuration example
feat(tour): revamped app to remove cookie dependency

to make a tour you now must set a 'current-step', you can then save the current step using any cookie module to keep track of if a user completed the tour
feat(tour): added support for multiple tours

renamed current-step to step, added unit tests, updated docs, also added tour callbacks for post-step and post-tour
