Rename some files and change some identifiers to be neutral to the
application name. This makes it simpler to change everything to a proper
name when cloning this project.
Document in the README how to find the remaining places to change.
Closes#20
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.
