    sidebar: allow to shrink the sidebar more
    
    so we can give more space to the document view, and
    also because sidebar minimum width was too much in
    verbose locales (because of bookmark button labels)
    which was almost causing it to switch to a two
    columns layout.
    
    Fixed by:
    
     - Switching the bookmarks section button labels
       from "Add" and "Remove" to be "+" and "-" along
       with corresponding tooltip and accesible names.
    
     - Set the label of the main sidebar toggle button
       to be ellipsizable, so the sidebar can be resized
       to reduce width even more.
