Remove components.all (#776)
It causes a lot of issues. To make this work:

* `shellFor` is updated to use `getAllComponents` instead of `.all`.
* `getAllComponents` is updated to work on the package rather than
  the package config.
* Tests updated to not use `.library` or `.exes.X` where appropriate.
* Documentation updated.
* Out of date examples removed.

As a bonus `shellFor` now takes a `components` argument that might be
useful for limiting the dependencies of the shell to just the ones
needed for the components you intend to work on.
