This field was introduced in
https://github.com/cockpit-project/cockpit/pull/4964 as "purely
informational for now", and isn't even parsed by cockpit.
package.json's version would only be relevant for publishing NPM
modules, but cockpit pages are not that.
Neither starter-kit itself nor our derived projects like cockpit-podman
or cockpit-composer have ever maintained these two fields, so just get
rid of them.
This makes the git tag the single source of truth for the version
number.
Fixes#200
A simple Vagrant VM based on fedora 25 cloud. It syncs `dist` to
`/usr/local/share/cockpit/<dirname>` on the VM.
Also decrease the minimum required version in `manifest.json` to match
the one that's currently in fedora 25.
