New Plastique in 4.2

The new Plastique style (see earlier posts about Plastique2) is making its way into Qt 4.2. It's not 100% done, but it's much better than what it used to be. Hopefully it'll be complete within few weeks after the snapshots are out. Beware of off-by-one rendering errors, though. Once y'all dig your hands into the upcoming Qt 4.2 snapshots, let us know what you think (and even better, help us spot more of those style bugs/annoyances!). :-)
