[pstricks] new \psaxes x and y labels

[Michael Sharpe]

Herbert,

The new arguments for \psaxes that allow positioning x and y labels  
are a fine idea. There seems to be a small glitch in the processing of  
keywords, in its current coding.

If I write

\psaxes[labelsep=6pt](-.5,-.5)(6.5,4.5)[$x$,-90][$y$,180]

then the labels on the ticks follow the specified 6pt separation, but  
the x and y labels do not. This can be worked around by

\psset{labelsep=6pt}
\psaxes(-.5,-.5)(6.5,4.5)[$x$,-90][$y$,180]
