chain commands, and let a project refine a catalogue stack

Browse Source 
myos build up logs host/fabio runs the three in order and stops at the first
failure, the way make build up logs STACK=host/fabio did. Leading words that
name commands are commands; the first word that is not one starts the stacks.

A stack found in several directories of the stack path is now merged rather
than shadowed, least specific first, so a project drops
stack/postgres/postgres.local.yml next to the catalogue's postgres.yml and
refines it. Settings hooks follow the same order, so a project can redefine a
default the catalogue ships. Neither engine did this before: the project
directory simply hid the catalogue one.

An unknown command now says so and suggests the command to type, instead of
printing the whole usage.

Stacks are looked up along the stack path, project first:
`./stack`, `../stack`, `~/.local/share/myos/stack`, `/usr/local/share/myos/stack`,
`/usr/share/myos/stack`. `myos doctor` prints the resolved path.

A stack found in several of them is **merged**, the project last, so a project
adds `stack/postgres/postgres.local.yml` next to the catalogue's `postgres.yml`
and refines it instead of replacing it. The same goes for the settings hooks.
