Lab::Measurement moves to Github

We've decided to migrate the primary Git repository of our code from Gitorious to Github. The new project page of Lab::Measurement is

https://github.com/lab-measurement/lab-measurement

and you can anonymously clone the code e.g. from the following URL:

https://github.com/lab-measurement/lab-measurement.git

This means we'll also be able to use the Github issue tracker in the future. The copy on Gitorious will eventually be removed.
