[criteria update] Interfaces

[Petr Schindler]

Because of changes in new anaconda [1] and after short discussion with
Chris Lumens, I propose to change this final criterion [2]:

'The installer must be able to complete an installation using all 
supported interfaces '

to

'The installer must be able to complete an installation using all
supported interfaces (graphical and VNC for F18)'

Reason (according to Chris): (Current criterion) again references 
multiple interfaces. For F18, it's really only going to be graphical and VNC.

Please, if you have some suggestions or notes reply to this thread. If
there won't be any objections I'll make changes during next week.
