--Bug fixes

-Allow group dragging and floating of dock widgets.
 --Note this has a bug where if tabls are grouped while floating, the tab position is placed on the bottom. It restores to the top when dropping on a dock location. I've filed a bug at qt.io
 -Make some tables auto size to their contents because some text appeared obscured on Linux.
 -The size of the xforms and palette tabs were preventing the main window from being resized to a small size on lower resolution monitors when docked. So rework scroll areas, minimum sizes and layouts to allow for a smaller main window.
