Flip arrays - ND support for fliplr and flipud, and replace flipdim with flip.
* fliplr.m, flipud.m: add support for N-dimensional arrays by making use
of flip(). Added new tests for ND arrays and defaults.
* flipdim.m: deprecate in favour of new function flip() which has exactly the
same syntax and is part of Matlab since R2014a.
* flip.m: new function copied from flipdim. Added tests for ND arrays and
defaults.
* matrix.txi: replace flipdim DOCSTRINg with flip.
* rot90.m, rotdim.m, del2.m: replace flipdim() with flip()
* NEWS: note deprecation of flip(), new function flipdim(), and ND support
for flipud() and fliplr().
