- Adds colored output
- Prints ".....F.....F.....F" and then the list of failed asserts
- Prints "FAIL" at the end of the example if any of the asserts had failed and not "OK".
- Adds a Spec that runs a nested Spec :)
- Some misc refactoring (use string interpolation....)
and let the `Spec.Reporter` print to `@env.err`
Pass in `Spec.Statistics.ForExample` to `example_ended`.
This prints output for an example like so: ....F..F.. followed by a list of failures.
Not to be mixed up with ASCII.

Prior to #17, `Spec.env` would return a real instance of the `Env`, which the spec examples could use in any way (for example, using it as the root of authority to create a capability object such as with `TCP.auth`). But #17 removed this in favor of a `Spec.Env` abstraction that wraps a possible `Env`, but may not hold a real one. This was done for the purpose of making it possible to test the effects of `Spec.Process.run` in `Spec.Process.Spec`, so that we could have tests in the `Spec` package that test itself. However, it was not actually necessary to remove the real `Env` from `Spec.env` to accomplish this - we can still pass the user code the real `Env`, but use a capturing abstraction for spec effects (i.e. exit code and printed output). This PR renames `Spec.Env` as `_Effects`, and brings back the real `Env` as being present at `Spec.env`, while the internal mechanisms that set the exit code and print results will use `_Effects` instead, such that these effects can still be captured and tested in our self-test.
