logic: maven project setup

* added option to create a Coati project from a Maven POM file
* show list of indexed file paths in maven project setup
* use FileManager to detect indexed files in project setup (except cdb)
* added Maven path to preferences window and added path detectors.
* fixed: QtDialogView::hideStatusDialog now also hides loader in status bar.
* refactored ProjectType
