deployments: add rejected status
fixes #12 (closed)
This allows to mark deployments as "rejected", which has the following effects:
- the deployments are listed in a separate list, so they can be distinguished from "not running"
- the the "deploy" and "submit" (targeturl) buttons in the deploy view are disabled
- if the deployment has already been deployed, it is no longer included in the API
@jakob does this work for you?
