the new statup dialog

This removes the old dialog, and the mess of having 
to select an empty document.

The new widget is just the old dialog in new 
disguise. But a new thing is that the colorspace is 
taken form settings->workingColorSpace and that 
default resolution is saved for next time the 
dialog is shown.

All in all a very nice and very visible 
improvement.
