Live/Install ISOs tests

[Gauvain Pocentek]

Hi list!

With the Xubuntu isos available, we need more tests, and have to see
what works fine and what doesn't work.
Ubuntu has a nice wiki page [1] to manage daily build tests. I've
started a Xubuntu variant [2] which needs to be
reviewed/changed/filed/updated. The Ubuntu page is changed with each
build. Maybe it's not the best solution for Xubuntu, and an other
organisation of the page could be done.

A "short testing HowTo" is available, a longer one could be written,
using the Ubuntu Long testing [3] page as a draft.

Thanks!
