[Zope] Changing tree icon colors

[Martijn Pieters]

I used my lunchbreak to add this as well, because it looked ugly without:

Example:
<!--#tree opened_decoration="/HelpSys/hs_obook" 
closed_decoration="/HelpSys/hs_cbook" 
childless_decoration="/HelpSys/hs_dnode"-->
Here the plus and minus symbols are replaced by the help system opened and 
closed book icons. Nodes without children are displayed with the helpsystem 
document icon.

This is a new patch, _replacing_ the previous one I posted (you did keep a 
copy of the old version, didn't you?).

Again, I'll post this patch to the Collector.
