switching ownership to organisation

Hello @cybertk, many thanks for your contribution to RAML tool stack!

I can see that this `grunt-raml2html` plugin is useful, if one uses RAML seriously - but...
- the support for this project seems to be dead, e.g. looking at dependencies
- and it doesn't seem to be popular, while it could be.

I was wondering whether this project would benefit more it it was github-transferred into the [raml2html github organisation](https://github.com/raml2html)? CC @kevinrenskers

I know it's not my project and I'm not the one to decide, but I'm sure that mentioning about `grunt-raml2html` inside `raml2html` would make much sense + switching the ownership would increase the probability of random people getting to know that your grunt plugin exists.

This is exactly what I did with my project and my open-source-mate - we had authored different projects and merged them together into: https://github.com/json-schema-faker. I added cross-information about relevant tools and after 8 months our project increased its popularity from 40 stars to over 220. Well, it's not about stars only - but it's just the convenience for the users to find relevant tools at one place.

No files, tests, or code entry points are identified. Review the six-comment discussion and the linked raml2html organisation context first; the issue is complete only when the ownership-transfer decision and any resulting repository move are settled.
