Add QColorPushButton and QColorToolButton.
QColorDialog::ColorDialogOptions is not yet handled by Qt Designer, I will have to handle that in some way.
Duplicate QColorDialog::ColorDialogOptions enum in QColorPushButton and QColorToolButton as the QColorDialog enum is not an available flag in QtDesigner.
Add QColorLineEdit, a line edit with a clickable button to choose a color.
