[New Features]
In the ProhibitLeadingZeros policy, added an exception for mkfifo.
Thanks, Evan Zacks. (GH#786)
Add color support for Windows platforms. Thanks, Roy Ivy III. (GH#700)
[Bug Fixes]
Recode Perl::Critic::Utils::all_perl_files() to use File::Find instead
of opendir/readdir. This solves endless directory traversals if
the directories contain circular symbolic references. Thanks, Tom Wyant.

Added CONTRIBUTING.md. Thanks, Jonas B. Nielsen.
