A couple more semi-essential fixes before 3.7gamma.  Including removal
of String>>asPlural, by popular demand.

It's possible to kill off the WeakArray finalization process, and it
never gets restarted.
This can cause many hard-to-diagnose problems.
This change set ensures that the WeakArray finalization process is
started at every start up.
It also shuts down the EventSensor's interruptWatcherProcess and
eventTicklerProcess at shutdown time (and starts them at startUp time,
of course).
(Removed InputSensor class>>startUp from original changeset which was
not needed. -dew)

5969asPluralRemoval -- Yoshiki Ohshima -- 29 June 2004
Remove asPlural."
