Got rid of the no-longer meaningful "depends" command. Consolidated the

replacement of the "install" command so that installation is always via
easy_install, but doesn't use the previous kludgy intereception technique.
Allow ``extra_path`` to be set, but ignore it, so that when easy_install
wraps a package that uses it, there won't be any confusion as to the
desired installation location.
