	and right Alt keys on	OSX

I commited the same functionality in the emacs-23 branch.  The patch you refer 
to makes none mean something else for right alt (follow left alt) than it does 
for the left alt (pass to system).  This is inconsistent, so I kept none to 
mean pass to system, and made a new value, left, to mean follow the left alt key.
