F18 Install test matrix - moved 'upgrade' testcases

[Josef Skladanka]

Hi,

since all the upgrade testcases are basically 'obsolete', as we are still waiting for FedUP, and Anaconda does not have any means of upgrading installed system, I created a new sub-category of 'Currently Unsupported Testcases' in the General Tests subsection of https://fedoraproject.org/wiki/QA:Fedora_18_Install_Results_Template and moved all the testcases.

If there are any more testcases, which do not make sense, or you really disagree with the change, then let me know on the list.
