Tidying up

Rename, archive and delete clients, projects and people.

client rename acme "Acme Inc"          # display name
client rename acme slug:acme-inc       # short name; paths become acme-inc/...
set p1 title:"Website v2" slug:site    # a project's name and slug
client archive acme                    # finished with a client: hide it, keep everything
client unarchive acme                  # bring it back
project delete p3                      # a project and its commitments
client delete acme                     # a client with all its projects
people                                 # everyone you've mentioned with @
person rename @ravi "Ravi Kumar"       # show a full name
person merge @rav @ravi                # fix a typo: move everything to @ravi

Archived clients and their projects are hidden from lists (clients --all and projects --all show them). Their open commitments stay in today and ls until you close them.

Deleting shows what goes with the item and asks you to type its name to confirm. Deleted items disappear from Keel; your daily backups from before still have them. In scripts, --yes skips the question, and --json without --yes never deletes.
