Non-functional _NET_WM_WINDOW_TYPE_DESKTOP when configuring shadows via the rules section

[raven2cz]

According to the documentation:

-c, --shadow
    Enables client-side shadows on windows. Note that desktop windows (windows with _NET_WM_WINDOW_TYPE_DESKTOP) never receive shadows, unless explicitly requested using the wintypes option.

This applies to the standard older configuration. However, if you use a new configuration with shadow, defined via rules, then _NET_WM_WINDOW_TYPE_DESKTOP no longer applies and everything gets shadows, which is incorrect.

I have to add rule:

 {
   match = "_NET_WM_WINDOW_TYPE = '_NET_WM_WINDOW_TYPE_DESKTOP'";
   shadow = false;
 },

How about match = "window_type = 'desktop'"?
