new xfdekstop mini-features

[Brian J. Tarricone]

hi all-

i just realised (by looking at the list archives) that it seems like 
none of my commits are going to the xfce4-commits list, so no one 
probably knows about the nifty little feature i just added that danny 
worked up.

you can now set the font that is used to draw the desktop menu.  put 
something like the following in your ~/.gtkrc-2.0 file:

style "xfdesktopmenu" {
    font_name = "Times New Roman 20"
}
widget "*xfdesktopmenu*" style "xfdesktopmenu"

you can name the style anything you want, but make sure the widget name 
is "*xfdesktopmenu*".  as you might guess, other rc-style settings will 
work too.  this will eventually be moved into a settable option 
somewhere so users don't have to mess with rc files.
