Use standard notation for IPv6 local loopback address ( ::1 instead of 0::1 )

[shoulders]

Within the documentation and config files of stubby you use the address 0::1 for the IPv6 local loopback address (which does work) but I cannot find anywhere else that uses this form, everyone use ::1

I think these instances should be changed to keep things easier to read unless there is a technical reason for this.

These are a few that I found README.md

listen_addresses:
  - 127.0.0.1
  -  0::1

As noted - this is an issue with our parser but I've added a comment directly into the config file to make this clearer

I'm closing this since the updated text was in 0.4.1 release but also marking as duplicate of the issue raising the underlying problem
