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.
Specifically:
* add Dnsmasq examples for reverse DNS for most of the RFC1918, 5735, and 6598 netblocks.
* Highlight some example options for dnsmasq that are probably of interest.
* Add a small section on reverse DNS testing
* Break out BINDs troubleshooting with Dnsmasq's troubleshooting
Not an exhaustive sweep, but should be helpful when introducing consul to new environments.
