Describe project status in README.md

[buhtz]

Hello,
it would help a lot users and potential new contributors if you could describe the current status of the project on top of your README.md.

From my current point of view, looking at the last commit and issues, I would assume the project is dead. But because of my own experience as a maintainer of several projects I am aware that this is not always the case.

It would attract new contributors to your project if they would know what is going on right know, what is the plan and if they can count on support from the current maintainers.
