Motivation:

The naming for the project key and name were slightly different in the POM and in the Sonar configuration. In order to be consistent, this should be changed.

Modifications:

* change sonar project name and key to the values from POM
* add Sonar output directory to .gitignore

Result

The naming is consistent.
