This changes the python[3]-django dependencies in packages to be
non-selecting, and adds an MDEPENDS line so that the *-src packages get
placed inside the django menu as well.

Added MENU:= to the src-package definitions in python[3]-package.mk,
so it does not import that setting from the binary package.

This change also updates the maintainer email to cotequeiroz@gmail.com, as

Not updating deps here, since that will be done in the next changeset that
will convert packages to the Python[3] packaging format.
