diff-lcs 1.3 release candidate 1spec-cleanup

- Updated testing and gem infrastructure.
- Cleaning up documentation.
- Modernizing specs.
- Silence Ruby 2.4 Fixnum deprecation warnings. Fixes #36, #38.
- Ensure test dependencies are loaded. Fixes #33, #34 so that specs can be run
  independently.
- Fix issue #1 with incorrect intuition of patch direction. Tentative fix, but
  the failure cases pass now.
