lick: add : to prints to match other vanes (#704)

This was bugging me:
```
lick init mkdir bus/.urb/dev
ames: live on 31519 (localhost only)
conn: listening on bus/.urb/conn.sock
```

This PR adds a `:` to all `%lick` debug prints so that it matches
behavior of all the other vanes:
```
lick: init mkdir bus/.urb/dev
ames: live on 31519 (localhost only)
conn: listening on bus/.urb/conn.sock
```
