Eclipse formatting rules should be provided for consistent source code formatting

Feature request

Expected Behavior - What where you expecting to happen?

There should be a file formatting_rules.xml (or similar) that can be imported into Eclipse.
It should contain formatting rules that are mandatory for the project.

Current Behavior - What happens?

Since default formatting in Eclipse is different from the current source formatting, if a reformatting of source code is done in Eclipse the resulting formatting is different. That leads to confusing diffs that hide the real changes.

Possible Solution

Provide a settings file with mandatory formatting rules.

Context

Notes and further information

[d-gs]

Should we use the Google Style Guide (https://google.github.io/styleguide/javaguide.html) on this project? They provide the eclipse formatting rule (and also for other IDEs), which can be imported easily (https://github.com/google/styleguide/blob/gh-pages/eclipse-java-google-style.xml).

Also, we should consider some maven plugin to check the styleguide on Travis.

We should force the usage of a standardized formater. We need to have a look on impacts and changes to the default (Eclipse) formatting.
