Provide Eclipse CS preferences to run checkstyle directly in eclipse

[Bananeweizen]

The build of this project fails on checkstyle errors. The Eclipse plugins however don't have any Eclipse CS configuration. Therefore during editing new checkstyle failures are not reported and will only be found later during the PR build.
I can create the necessary preferences in the Eclipse projects, if you want me to.

If you do it, I will merge it.

You can also use Save actions to save time, for example, for trailing spaces:

• Window -> Preferences -> Java -> Editor -> Save actions -> Perform the selected actions on save -> Additional actions -> Remove trailing white space on all lines
• Window -> Preferences -> Java -> Code style -> Formatter -> Edit -> Indentation -> Tab policy -> Spaces only

What are the other CS rules that bores you?
