Link to Python-related docs are broken (all the links should be checked, honestly)

[IoIxD]

There's a link to http://fontforge.github.io/python.html#Font, which 404s now and has since moved to https://fontforge.org/docs/scripting/python/fontforge.html#font

That said, there's many links to fontforge.github.io, and it seems like that has moved to fontforge.org. You should likely check all the links and find their equivalent
