[PyQt] Problem using QFormLayout in QtDesigner and pyuic4 in qt 4.4

[Pavol Mravec]

When I use a QFormLayout in QtDesigner and generate python module
using pyuic4, pyuic4 finishes with error: Unknown Qt widget:
QFormLayout. I use qt 4.4 on windows xp compiled with msvs 2008
express edition and pyqt 4.4.2. The expected result is a working
generated python module. When I switch from QFormLayout to
QGridLayout, everything works correctly.

Example pyuic4 output: pyuic4 widget.ui
