Review request for kdelibs and Laurent Montel.


Description
-------

Do not connect colorSelected to _k_colorChosen otherwise two bad things happen:
 a) Selecting a color and canceling still changes the color of the color button (this is KColorButtonTest::testChangeAndCancel that fails without my change)
 b) If you are in Recent Colors there's a crash (bug 313984 because a lot of bad things happen (this is not in my tests, will add later if you guys agree this is the correct fix))

Laurent added
     connect(dialog, SIGNAL(colorSelected(QColor)), q, SLOT(_k_colorChosen()));
to make sure that double click worked, thus i've added KColorButtonTest::testDoubleClickChange() to prove it still works after my change

Comments?

Developed against master, plan to apply against KDE/4.10 too
