#21 MMCLib2 - Icon handling bug

[samareth]

I only noticed when I altered the code in my constructor
of my snapin that, if a particular icon is not used by any
current node added by the Snapin constructor, The
constructor of BaseNode won’t find the icon later when
the node is added by a menu handler even if it is
correctly added to the project. I created a workaround
in my code by accessing the snapin in its constructor to
call AddImage over and over until I had added all the
icons in my images folder.
