Start with |start %desk %app-name
Everywhere in the kernel that we deal with marks, we infer the app it's
connected to and use the marks from that desk.
Also some light renaming in gall, especially path->wire and
current-agent->yoke.
Subsequent tasks:
- Dojo needs a syntax to run generators and threads from other desks
- The home desk should be split into at least a minimal base desk and
big "userspace" desk. Dill's initialization logic should be updated
to handle
- |show-package, |install, and |uninstall should to be written
- Clay should have smarter handling of system versions instead of just
ignoring what's on each desk. It's not clear that this will work
correctly when sys updates right now.
