Scala 2.x macro pages have dead links to scalamacros.org

[bicknrown]

the website scalamacros.org is no longer being used for what it was originally intended for when this documentation was written, so I have linked to the github repository which contains the original data. https://github.com/scalamacros/scalamacros.github.com

It may be worth it to look into archive.org for this purpose, if it is felt that the repository used is not sufficient.

In the event the repository disapears, I have created a fork, and plan use it for archival purposes. This fork is welcome to use by the scala project in such an event. https://github.com/bicknrown/scalamacros.github.com/
