Modified dependencies to imglib2 and imlib2-realtransforms instead
imglib2-examples.  to that end, moved CATMAIDRandomAccessibleInterval
here (where it belongs, examples can retain a duplicate), removed
dead code using ImageJ displays and moved Converters in ImgLib2---make sure
to have ImgLib2 at 2a21b649b71b20b9187b090708cc9a1798a4eeb8 or later
