    Fix #272: remove obsolete xml files.
    
    Both:
    - src/concepts/fonts-and-text.xml
    - src/menus/windows-show-docks.xml
    were not used anywhere in the generated
    manual so let's remove them.

 src/concepts/fonts-and-text.xml  | 113 ---------------------------------------
 src/menus/windows-show-docks.xml |  47 ----------------
