outdated config files?

[Bananeweizen]

If I remember right, the files in https://github.com/checkstyle/eclipse-cs/tree/master/config are used during building the project. At least the 2 import control files should have a higher version meanwhile, so probably all those files should be synced with the main project.

The checkstyle files will also have to be reviewed as per #351
