SF.net SVN: frontierkernel:[1836] Frontier/trunk/Common

[<ted...@us...>]

Revision: 1836
          http://frontierkernel.svn.sourceforge.net/frontierkernel/?rev=1836&view=rev
Author:   tedchoward

Log Message:
-----------
We can now plot IconFamily data stored in the ODB

I added a function that loads the IconFamily data currently stored in
the odb, load it into an IconFamily data structure and use Icon Services
to render the nodetype icon in the outline.
