Maven JDEE Plugin

There are already plugins holding a lot of information we need when writing the project file. Especially the javadoc and the java plugin contain several properties that we should reuse.

Some examples:

maven.compile.deprecation
maven.javadoc.private
maven.javadoc.doctitle
maven.javadoc.destdir

At the moment we're using the target directory to direct the compilation and javadoc output produced by JDEE to.
