[CONTRIBUTING.md][README.md] Add Contributing Guidelines with CLA. (#261)

This pull request reflects a change in the contribution process which greatly simplifies accepting contributions from W3C members and non-members alike, as it drops the requirements for filling-in Grant II forms. This has of course been vetted by W3C legal.

You're welcome. :)
