Style/IpAddresses fails on 4 point version numbers

[mockdeep]

The following line in my Gemfile caused Style/IpAddresses to report a failure:

gem 'autoprefixer-rails', '10.0.0.2'

Not sure if there's a graceful way to tell the difference between IP addresses and versions. I suppose you could check for gem lines or references to version or VERSION to cover most cases.
