a few highlights: * BLayout now derives publicly from BLayoutItem * Added BAbstractLayout class, which our layouts now derive from * updated layout builders to avoid creating views when they don't need to * updated layout classes * updated AboutSystem to fix a little regression * more details on #6407 * please tell me about any regressions, I've tried to find them all, but some may have slipped by. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38207 a95241bf-73f2-0310-859d-f6bbb57e9c96
