Easily contributing to Licode docs

Dear all,

following with the improvements in the contribution procedure, we now introduce a new way of managing documentation in Licode.

We have configured a ReadTheDocs account to keep Licode documentation in the website up to date with every source code update. Thanks to this service we also have a history of the documentation for every release, what fits very well with the new versioning paradigm we have recently adopted.

On the other hand, thanks to the new approach it is simpler for the community to contribute documentation, for fixes, improvements and for introducing changes when contributing new features. You can find the details regarding the procedure in Licode Contribution Guide.

As always, we hope this helps to make Licode even better :slight_smile:
