Review request for Plasma.


Summary
-------

the tabbar widget can behave both like a tabwidget and a plain tabbar, the behaviour should be a bit different, in particular it did behave really bad when in a panel.
this patch removes the centering and makes the tabbar to take up all the width when it's not like a tabwidget and there is some sizepolicy/preferred sizes setting fixes that makes it behave better in a panel (especially vertical ones)
code probably doesn't look reeeally well, but in particular with that double meaning of tabbar and tabwidget didn't come to my mind something more elegant :)
