Added a html_footer file for display at the bottom of each doxygen page

instead of the doxygen default "Generated ... by doxygen"
(copied from FLTK 2.0).

This should be discussed, and optionally removed or modified.

Added 5 different navigation elements to the bottom of development.dox.
Please check, what you like most (if any).
