Added 4 different quickstarts, together with a distribution module:

- `modeshape-servlet` - is the porting of the `modeshape-web-example` module from the examples repository
- `modeshape-ejb` - is a quickstart that shows how to use ModeShape from 3 different types of EJBs: Stateful Singleton, Stateless CMT and Stateless BMT.
- `modeshape-cid` is a quickstart that show how to use CDI together with `@Producer` and `@Consumer` methods to inject a ModeShape session
- `modeshape-cli` is a quickstart which contains a couple of CLI scripts that are used to setup/clear the repository.

All quickstarts contain remote Arquillian based unit tests.
