x(yz)label.m, title.m: Update to use new __plt_get_axis_arg__. * scripts/plot/title.m: Update to use new __plt_get_axis_arg__. Rename h to hax. Redo docstring. * scripts/plot/xlabel.m, scripts/plot/ylabel.m, scripts/plot/zlabel.m: Update to use new __plt_get_axis_arg__. Rename h to hax. Redo docstrings so that ylabel and zlabel have their own rather than pointing to xlabel. Add check for using prop/val pairs to %!test block. Fix passing color argument so that user prop/value overrides default.
