The DocumentViewer demo was originally developed as a self-contained
application. Its dependency to PdfWidgets has lead to splitting it up
into plugins: ba61af0bf3
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.
