    Improve detection of input device source type
    
    This detection code is not 100% reliable, but it should fare much better
    than the current code, which just compares the device name to a fixed
    set of strings.  Many applications depend on erasers being recognized
    reliably, so we start by checking for a device name containing the
    substring 'eraser'.
