Removed unused clone of exec_helper, which is called only in qtGui.py.
Removed cloned (and not-quite-accurate) docstring for PosList class defined in leoNodes.py.
Moved @doc part into docstring in convertVnodeToWeb and replaced cloned code with simple inline code.  Such clones are very bad style.
Replaced unnecessary cloned code with duplicate code.  This use of clones if very bad style.
Removed all clones in leoProjects.txt and leoToDo.txt, replacing them as appropriate with comments.
Replaced section reference in pylint-leo.py with local clones in my personal copy of leoPy.leo.
