[Qgis-developer] Minimum qt version - bumping to 4.6?

[Nyall Dawson]

What's the chance we can get the minimum qt version bumped up to 4.6?
There's a large number of issues relating to rotation of composer
items [1] which would be much easier to fix if I can use
QGraphicsItem::setRotation and QGraphicsItem::rotation, both of which
were introduced in 4.6.
