Add per window type option full-shadow

When this option is enabled for a window type, shadow will be drawn in
areas that are obscure by the shape of the window.

Useful when the given window type has parts of the window transparent,
and you want to have shadows in those areas.

Fixes #45

'WINDOW_TYPE' is one of the 15 window types defined in EWMH standard: "unknown", "desktop", "dock", "toolbar", "menu", "utility", "splash", "dialog", "normal", "dropdown_menu", "popup_menu", "tooltip", "notify", "combo", and "dnd". "fade" and "shadow" controls window-type-specific shadow and fade settings. "opacity" controls default opacity of the window type. "focus" controls whether the window of this type is to be always considered focused. (By default, all window types except "normal" and "dialog" has this on.)

Following per window-type options are available: ::
fade, shadow:::
Controls window-type-specific shadow and fade settings.
opacity:::
Controls default opacity of the window type.
focus:::
Controls whether the window of this type is to be always considered focused. (By default, all window types except "normal" and "dialog" has this on.)
full-shadow:::
Controls whether shadow is drawn under the parts of the window that you normally won't be able to see. Useful when the window has parts of it transparent, and you want shadows in those areas.
