Add Json, text and pdf document viewer demo Add a demo with a combined viewer for Json, pdf and text documents. The example demonstrates how to create an application, utilizing a main window with static and dynamic toolbars, menus and actions. Type specific viewers inherit from an abstract viewer class. The Json viewer implements an abstract tree model for QJsonDocument. The example demonstrates a few useful application features, implemented with QtWidgets and QSettings, to (re)store properties: - Detecting file content types with QMimeDatabase - Changing and restoring override cursor when hovering over a widget. - Basic printing support.

DocumentViewer demo: Make plugins re-usable The DocumentViewer demo was originally developed as a self-contained application. Its dependency to PdfWidgets has lead to splitting it up into plugins: ba61af0bf3281cb93a4b8c5ae1410e5015766fa3 The new architecture re-uses the viewer objects, but it doesn't reset them properly. This is why viewer-specific UI-assets (menus, toolbars and buttons) get duplicated. This patch adds cleanup functionality and removes duplications.
