QToolButton. Features: - context menu items have been moved to the attached menu button - new gui widget QgsColorSwatchGrid, which displays a grid of colors - new class for QgsColorScheme, which generates colors to show in a color swatch grid - new class QgsColorSchemeRegistry, with a global instance containing default color schemes. QgsColorButtonV2 accepts a color scheme registry, to control which schemes to show in the popup menu as color swatch grids. - color button can have a default color - color button can also be quickly set to a totally transparent color - c++ and python unit tests for all core components
