Todd Gamblin 423d3e75ab env: clean up command access to the active environment ...

- all commands (except `spack find`, through `ConstraintAction`) now go
  through get_env() to get the active environment

- ev.active was hard to read -- and the name wasn't descriptive.
  - rename it to _active_environment to be more descriptive and to strongly
    indicate that spack.environment manages it
