.idea: Add Run-Configurations

Added run-configurations for clean/install and
Sonar (mind that you have to provide a
Sonar-Profile in your settings.xml to make it
work).
Reformat Code

Reformat according to codestyle. Especially
changed: Introduced asterisk-import.

Idea: If you already used several classes of a
package it is most likely that you will use
other classes of the same packages.
Workspace Documentation

Some initial workspace documentation.
