[BioPython] Documenation link is dead on the download page

[Danny Yoo]

The Documentation link on the sidebar, from:

    http://biopython.org/Download/

goes to:

    http://biopython.org/Download/wiki/html/BioPython/BiopythonCode.html


but the link is broken: it should probably go to:

    http://biopython.org/wiki/html/BioPython/BiopythonCode.html

instead.


This 'Docs' sidebar bug also affects the Projects and Related pages:

    http://biopython.org/Projects/
    http://biopython.org/Related/


Hope this helps!
