Allow local env files for each Rails environment, and host family. Fix dotenv file load order and overriding values.

[cfurrow]

Suggesting this change to be a major bump in version as it changes the underlying behavior.

The Problem

While doing some local testing with VCR, I realized my .env.local was superseding values set in .env.test. I did not want this.

• .env.local is NOT committed to the repository, and therefore is local to my machine
• .env.test IS committed to the repository, and shared by all devs + our CI environment.

My VCR tests were using MY local credentials in .env.local, which is not what I wanted it to do. The specs I was writing could/would fail in CI, as the credentials and VCR request matchers would be in conflict.

The solution

Allow for more fine-grained .env filenames, and make sure the test environment does not use my .env.local, but instead would rely on .env, .env.test, .env.HOST_FAMILY, .env.test.local and .env.HOST_FAMILY.local. Then I could rename my .env.local to .env.development.local and keep it out of the repo, and out of the test environment.

Added rspec tests

I noticed there was a spec directory, but no valid specs. And rspec was not a dependency of the gemspec, so I added it, plus rails, in order to get the rspec tests passing and validated.

This looks like a great change to me! Thanks for fixing the specs in addition to making things a bit more predictable.

This change is technically breaking, so I'd probably recommend a major version bump. We can definitely do that in a separate PR.

This is awesome, thanks so much! I think we'll need to ping @wireframe to do the actual publish of the gem once this is merged.

[wireframe]
