completed step 1 refactoring task scanner publisher to be used with build settings configurator approach.
 - added an additional hierarchy layer for task scanner build settings
 - added a maven build settings class
 - refactored controls of AbstractTaskScannerBuildSettings (former TaskScannerPublisher) to be in line with the handling and naming conventions in AbstractCodeStylePluginBuildSettings

Be aware that the changes made to TaskScannerPluginTest have been done automatically by IntelliJ during the refactoring actions mentioned above. Further refactoring is still necessary and will be done in step 2.
