Move to Github

Finally came across a migration guide (subversion to git), one that actually worked:

https://git-scm.com/book/en/v2/Git-and-Other-Systems-Migrating-to-Git

Main issue with the migration was the sub-division of the repository into base/addons/incubator/etc. However, I decided to skip really old code and just start at a revision after the sub-division.

You can find the repositories now here:

• https://github.com/Waikato/adams-base

• https://github.com/Waikato/adams-addons

• https://github.com/Waikato/adams-incubator

• https://github.com/Waikato/adams-libraries

• https://github.com/Waikato/adams-spectral-base

• https://github.com/Waikato/adams-applications

Contributing should be much easier now, so go on, fork the repos! :-)
