Scrupulous Syntax Highlighting for /etc/hosts

Features

• It highlights IPv4 and IPv6 addresses rigidly. For example: it won't match the impossible movie IP-address 189.23.290.13. This makes it easier to spot errors.
• It styles private IPv4 address-ranges and public IPs differently. It supports all three private ranges: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.

Installation

Install via Package Control.

Acknowledgements

The regular expressions for IPv6 by David M. Syzdek were found on stackoverflow.com. I had to rewrite them in a different format so any faults or mistakes are probably mine.

Michael B Lyons provided fixes and some great additions.
