[hse-ui] Improved Popup-Windows
- There should be an option to run a dialog synchronous or asynchronous. An asynchronous dialog box is often needed when one want to display some information but don't want to block the underlying execution.
- The popup-dialogs could get a fresh design with NXG-controls, more white space and more colors.
- Functions to close a dialog window programmatically, e.g. with a user event. In addition.
- Wrap the dialog windows functionality into a class.
