Blessing is now the time that bootstrap tarballs are created.
There's a banner that goes into the global manifest (stored in
scripts/admin/banner.txt).
The global manifest.json is now entirely generated: there's no record of the
current version stored in git.
Have not yet updated launch-meteor or install-template.sh or the fake release
for this brave new bootstrap world, or https://install-bootstrap.meteor.com/.
while I'm at it, fix it so that it actually works if the package's on_test tries
to use() itself (which is common). This previously did not work with
--package-dir
remove unused websocket (if we need it again outside of the streams package
we'll probably be wrapping it in another npm module anyway)
shrink dev bundle version number location to just one place!
