Commit to beat the feature freeze :-)

Add new tabs to QPrintDialog to set CUPS printing options. This includes n-up printing, page borders, banner pages, mirror pages, and job scheduling.

This change requires the final release version of Qt4.4 as it relies on a patch not present in the RC or betas. The tabs will also only appear in apps that call KDEPrint::createPrintDialog to obtain a QPrintDialog (I'll be fixing most apps that don't currently do so).

What doesn't work: the CUPS detection routine needs more work, and the Job Options table is a bit crashy, but everything else should be fine. Oh, and the ugly n-up icons (borrowed from KDE3) need replacing in the style and size of the existing Qt Colour Mode icons (see options tab).

Memo to self: Now I must send Danny the promised article...
