I was reviewing some docs and found a few issues.
1. Fixed some spelling mistakes.
2. Re-formatted some paragraphs.
3. Changed some potentially loaded language.
4. Fixed some grammar issues.
5. Tried to consistently use syntax-highlighting.
6. Fixed post-period spacing.
7. Fixed some formatting issues and inconsistency.
8. All "notes" are either proper notes or re-written.
The change fixes a minor bug in the document that says consul supports back to version 0 when the example output says version 1, and makes the document less ambiguous by having a different "current" protocol and earliest supported protocol.
