Khronos Chapters update!

It's been a very busy few weeks for the Khronos Group chapters. We've added three new chapters: Paris France, Washington DC and Wroclaw Poland. There is a good selection of upcoming meetups as well:

- Computer Graphics on the Web: Dec 8, 2015 - Melbourne, Australia
- First Khronos Wroclaw meetup + VR: Dec 9, 2015 - Wroclaw, Poland
- Image Processing with WebGL: Dec 10, 2015 - London, Britain
- WebGL Developers Meetup: Dec 17, 2015 - Milano, Italy
- OpenGL for beginners part 1: Jan 06th, 2016 - Naritaweg, Amsterdam

Errata: We originally said Seattle Washington... our mistake, our latest chapter is in Washington DC.
