[Jonh Wendell <jwendell src gnome org>]

commit aa3d4efa0f90a3bc310f6d9eecdfc4d2d8718949
Author: Jonh Wendell <jwendell gnome org>

    Added "has-screenshot" property into VinagreTab
    
    It means that a tab has the ability to take a screenshot. VinagreNotebook
    will use that property to sensitive the "Take screenshot" action.
