Show list of currently seeded repos

[maninak]

Similarly to how #55 helps show the current status of the current project, it would help to advertise the current status of our local node. There's many parts of that status, but here we'll focus on showing a list of seeded Radicle projects.

The UI will look like the following found on the native SCM's Remotes View

It would perhaps make sense to add this view under a new Radicle View Container dedicated to non-currently-opened-repo state. In such a case creating a new icon for each of the existing and new view-containers would be a good idea.

Acceptance Criteria:

1. new View Projects lists all seeded Radicle projects with
   1. project name as title
   2. RID as description (maybe also more project info on hover tooltip?)
   3. current seeding scope (is it even possible to know that?)
   4. whether the repo is private
2. each item in the list has, on hover, buttons for the following actions
   1. copy RID
   2. unseed (see Add rad seed/unseed commands #54)
   3. change tracking scope
   4. clone
