OLA 0.9.0 Release, move to GitHub and new website.

[Simon Newton]

It gives me great pleasure to announce the 0.9.0 release of OLA. We
had 9 authors contribute to this release with approximately 47k lines
of code added or changed. The new .debs and Pi images have been
uploaded, macports and the other .debs will follow later in the week.

Along with the 0.9.0 release, we have a new website,
http://www.openlighting.org . Also the git repository has moved to
github (https://github.com/OpenLightingProject/ola ) , so if you're
using a git image you'll need either need to upgrade to a new image or
change the remote in your git clone.
