Java REST API implementation.

[dougculnane]

Add 2 new projects with API code from:

• Markus's api branch
• message java objects for serialization
• an working rest client implementation in java
• unit test against api if environment vars are set

The api project is a POJO implementation of the API. It can easily be used as a dependency in other environments.

The client implementation can be copied and used with the users preferred dependencies (as I will do in openHAB)

The implementation only has the basic information from the API. As the API is documented we can implement more.

It would be great to release this so I can use it as a dependency and do PR for a working basic info binding in openhab as I think this is better than a not working binding...

Hopefully over the Christmas holidays i will find time to try and document an implement the API more.

Could you check that those work, before I release them and push them to central?
