Dumping automatic dependency management

Developing without attached Javadocs is a pain. As it was not possible to have
the java docs included automatically by Eclipse with the prior approach, we
resort to a manual dependency management. This makes WatchDogLib redundant.

Closes #10
Converting required plug-ins to imported packages

Generally, imported packages offer a greater flexibility than required
plugins. Therefore, we want to get rid of all required plugins and use the
more dynamic imported packages instead, which does not rely on a specific
implementation of a certain package.
