    Use "resize" property and fix a bug in gdl_dock_paned_set_orientation
    
    This Commit allow us to use "resize" property. It remove some dead code in gdl_dock_paned_dock function. 
In this function property "preferred_height", and "preferred_width" was checked against -2, while minimum 
value is -1. Typo in gdl_dock_paned_set_orientation function was fixed. Don't really know is it a right way 
to change child property in function gdl_dock_item_set_property i used.
