Update _posts/12-01-01-Community.md

There is a large PHP Programmers community on G+ community. There are around 9000+ PHP programmers from around the globe are still active.

I have added that link to this doc. Hopefully it will help the people
who trust phptherightway. It would be great if you can merge this.

Thanks,
