* Repo collab now supports basic default roles developer/user/guest like
project collab does
* User/Anon collab for repos and projects are now stored as fields instead of
in dedicated tables, there was never a need for dedicated tables but I didn't
see that before
* Repo push op is now part of `ProjectOperation`
* `RepoRole` and related code has been entirely removed, only project roles
remain and they're used for both repos and projects
* This is the first not-totally-trivial DB migration in Vervis, it's automatic
but please be careful and report errors
* When adding collaborators, you don't need a custom role. If you don't choose
one, a basic default "developer" role will be used
* If you don't assign a `ProjectCollabUser` role, a default "user" role is
assumed for logged in users, otherwise a "guest" role
* The "guest" role currently has no access at all
* Theoretically there may also be a "maintainer" role allowing project
sharers/maintainers to give maintainer-level access to more people, but right
now maintainer role would be the same as developer so I haven't added it yet
It already had one, but it didn't have a public key and it was using the old
mess of the Vervis.ActivityStreams module, which I'll possibly remove soon.
It's hopefully more elegant now.
A workflow is a new entity in Vervis. It defines the workflow of a
projects' ticket system. That includes the possible ticket states,
custom ticket fields, various filters and so on. All ticket system
customization is currently planned to be managed using workflows.
Currently workflows are private and per sharer, but the plan is to
support public workflows that can be shared and cloned.
My implementation in Haskell does work, but ref discovery also includes
capabilities. Since I'm going to use the git binary for the next steps,
I need the git binary to specify here which capabilities it supports.
