[PyQt] [UIC] uic.properties _gradient factory returns wrong item

[Giuseppe Corbelli]

Hi all
Wanting to apply a gradient background to some buttons I ended up having 
a custom palette with gradients (not sure if this is a side effect or 
something needed to have the stylesheet work).

However apparently the uic.properties._gradient factory is returning the 
string 'gradient' instead of the actual Q*Gradient instance.

See uic.properties at 277
