website: use only native names in language menu
On our main website www.freebsd.org top right we have a language menu.
It shows "English", "Russian" and "繁體中文", mixing English names with a
native one.
The usual convention is native names for all: English, Русский, 繁體中文.

man.cgi: enable shortcuts URLs with a dot + section
E.g. man.freebsd.org/socket.2
This is equal to the existing shortcut man.freebsd.org/socket/2
and similar to other manpage services (NetBSD, Debian etc.)
website: fix sub-menu in the header for mobile devices
If the browser width is less than 1300 pixels: click top left
on "About" and the sub-menu will not open anymore due the missing IDs.
