Added an option to just maximize the window instead of place in the fullscreen state.

	Option --no-fullscreen maximize the window, instead of place in the fullscreen state.
	Usually the menu is a window in the fullscreen state, but maximized looks better with the GNOME-Shell.
Close the window when it lose the focus.
Use alpha form GdkRGBA instead of Afill (_a_fill).
Colorable the black outline.
Debian packaging version 0.0.0r59.
