Modify config to include _docs-4 in generated site (#458)

These changes will include the _docs-4 directory in the
generated site at `docs/4.x`. All pages will have a warning
at the top to tell the reader that these are draft docs
for an upcoming 4.0 release. These pages are not listed
in the `Documentation` drop down menu.
