New issue 450 by icarnales: ManageDocks should check for multi window types  
in _NET_WM_WINDOW_TYPE
http://code.google.com/p/xmonad/issues/detail?id=450

According to the spec:

_NET_WM_WINDOW_TYPE

_NET_WM_WINDOW_TYPE, ATOM[]/32

This SHOULD be set by the Client before mapping to a list of atoms  
indicating the functional type of the window. This property SHOULD be used  
by the window manager in determining the decoration, stacking position and  
other behavior of the window. The Client SHOULD specify window types in  
order of preference (the first being most preferable) but MUST include at  
least one of the basic window type atoms from the list below. This is to  
allow for extension of the list of types whilst providing default behavior  
for Window Managers that do not recognize the extensions.

What steps will reproduce the problem?

1. Launch a program with multiple window types like DOCK and NORMAL (tested  
with unity-2d panel and launcher)

What is the expected output? What do you see instead?

The window should be ignored and a gap must be created to accommodate it.  
Instead the window is treated normally.

What version of the product are you using? On what operating system?

0.9

Are you using an xmonad.hs?  Please attach it and the output of "xmonad
--recompile".

Any config with ManageDocks (tested with desktopConfig and manual  
ManageDocks) will do.

Please provide any additional information below.

I think checkDock function should be in a more generic place like  
Hooks/ManageHelpers that are currently using the isInProperty function to  
check for property values.
