cpumem applet patch

[Robert Mibus <mibus bigpond com>]

This patch adds pause/continue to the cpu/mem applet. (my computer is slow &
the cpu applet causes a momentary 'freeze' in GL apps, ie games).

the patch applies cleanly to gnome-applets-1.1.8 & 1.1.9 (& i assume 1.1.90,
but i haven't grabbed that yet :)

(pls. tell me if you want the patches in some other form)
