hard-dep for Qt 4.8

[Hugo Pereira Da Costa]

Personally, I think making Qt4.8 mandatory for KDE4.8 without strong 
reasons to do so raises the barrier a bit too high for casual 
contributors willing to fix bugs. I personally find Qt harder to compile 
than kde and am quite reluctant to update, just to be able to still fix 
bugs in oxygen.
