Double-click on preview style should add it to "Selected"

[Siedlerchr]

Is your suggestion for improvement related to a problem? Please describe.
I always want to use a double click to transfer a style to the other list

Describe the solution you'd like
Preferences → Entry Preview

1. Double-click on one of the styles in "Available" should add it to the "Selected" list view
2. Double-click on one of the styles in "Selected" should remove it from the "Selected" list view

Additional context

Implementation notes:

PreviewTab under gui/preferences needs to be adjusted.
Add a click handler withOnMouseClickedEvent to the listViews and check for a double click
