    Rework our icon management
    
    They are now all stored in a directory structure similar to the final
    installation target, so no more copying of images during build is needed.
    Both Makefile.am and CMakelists.txt behave the same now.
    
    Some additional cleanups:
    - move stock_move related images to art; they aren't used so don't need to be installed
    - clean up icon loading
    
    There is one harmless warning still at run time about not all requested image
    sizes being found. This is odd because they are all installed. I suspect gtk
    no longer searches for these resolutions. Perhaps we just shouldn't run the
    check on them. The application works fine even without the images in the
    requested resolution.
