Upgrade minitage versions

This includes a fix in minitage.recipe.egg, which makes sure that the
eggs order isn't shuffled, see minitage/minitage.recipe.egg#1.

The lack of maintaining eggs order has caused a problem if
`adhocracy_service` and `adhocracy_theming` were included in
`buildout.cfg`: If `${buildout:directory}/src` was added to the path
below `js.bootstrap`, the bootstrap resource wasn't delivered by
fanstatic in kotti.
