Rewrite stdlib tests in Blueprint

[hrs]

Since the standard library can't throw errors, a standard test framework wouldn't need to catch them (yet). None of the current (RSpec) stdlib tests rely on exception handling, so let's not worry about that yet.

• Build a standard testing framework, tested in RSpec.
  • Should have visual output (we'll need to implement display)
  • Should be able to return a non-zero exit status.
• Rewrite stdlib tests in that framework.
• Run those tests when we run rake. Make sure CI can run them.

Travis can totally run the tests. Sweet.
