env: environments can be named or created in directories

Browse Source 
- `spack env create <name>` works as before

- `spack env create <path>` now works as well -- environments can be
  created in their own directories outside of Spack.

- `spack install` will look for a `spack.yaml` file in the current
  directory, and will install the entire project from the environment

- The Environment class has been refactored so that it does not depend on
  the internal Spack environment root; it just takes a path and operates
  on an environment in that path (so internal and external envs are
  handled the same)

- The named environment interface has been hoisted to the
  spack.environment module level.

- env.yaml is now spack.yaml in all places.  It was easier to go with one
  name for these files than to try to handle logic for both env.yaml and
  spack.yaml.
