[Jason Harris]

CVS commit by harris: 

Implemented Manual stepping of the clock (wish #65476).

Press the "." / ">" key to advance one step forward; press the "," / "<" 
key to advance one step backward.  The stepsize is set by the TimeStep 
widget in the toolbar.

If the clock is running, it will be automatically stopped when one of the 
manual-step keys is pressed.

On my keyboard, "," and "<" appear together on the same key, and "." and 
">" are on another key; is that generally true for all keyboards?

At this point, there is no GUI way to do the manual-stepping.  It would 
make sense to add these buttons to the TimeStep widget, but it is already 
pretty complicated.  What do you think?
