Fix non-composited CSD windows

Apply Raveit65's  https://dl.dropboxusercontent.com/u/49862637/Mate-desktop/Bugs/blackmate_csd.patch 

using border radius 0px for solid-csd (w/o compositor) fixes the black corners from csd windows, which comes from shadows. (gtk+ or marco issue)
border color is the same like for other windows
missing selector messagedialog.csd
settings for backdrop state, testable in cinnamon.
new deprecation GtkComboBox-shadow-type which spams the terminal, i don't know if there is an replacement for it.
