Patch for LXPanel to close windows on middle click.

I like using middle-click to close tabs in Firefox, and I would like to be able to close windows by middle-clicking their icon-entry on the taskbar in LXDE. Unfortunately, it can only be done by editing the source of lxpanel, which is the LXDE taskbar.

For Debian, you need to get the source code:

 apt-get source lxpanel  
 sudo apt-get build-dep lxpanel  

Then you need to apply this patch:

      {  
 -      /* Middle button. Toggle the shaded state of the window. */  
 -      Xclimsg(tk->win, a_NET_WM_STATE,

      }  
      else if (event->button == 3)  
      {  

And install it:

 ./configure  
 make  
 sudo make install  

Now you can close windows with middle click on taskbar.
