top: preserved those new '4' and '!' toggles in rcfile

Browse Source 
This patch will address Craig's feedback regarding the
original implementation of top's two new toggles. It's
likely other users would have questioned why they were
not saved also, once they discover these new features.

And, since the minimum terminal width was just lowered
to 80 columns, the default for window #1 is also being
changed to show the individual cpu graphs two abreast.

[ assuming no '--disable-modern-top' for ./configure ]
