delombok everything

[tyrasd]

This uses the lombok-maven-plugin to delomboking all java classes.

• fixes missing getters/setters in javadoc (Lombok hides Javadoc for public getter&setter #74)
• helps static code analysis (checkstyle, CMD, CPD, etc.) to not choke up on lomboked classes

It would technically suffice (I believe) to only put the classes which actually use the lombok annotations into the /src/main/lombok/ directory (and leave all "regular" classes in /src/main/java), but I guess this way is a bit easier to manage since then one would not have to think about the need to move files when starting to use lombok more and more.

TODO:

• check if there are any references (in code comments, documentation, etc.) to /src/main/java which need to be updated
