Greg Ercolano a657069cc5 Checked in SebHoll's API mods, fixed indents.
o Added user_data() to Fl_Tree_Item
	o Added insert() and add() methods that allow specification of Fl_Tree_Prefs
	o Changed Fl_Pixmap args to Fl_Image for more flexibility
	o Fixes for positioning of items in the presence of user icons
	o find_children() changed from protected -> public
