[Squeakfoundation]Testing Coordinator volunteer

[Doug Way]

Since Marcus Denker is doing a fair amount of work with maintaining the
test-related packages for Squeak (SUnit, BaseImage Tests, and some other
package tests), I went ahead and added him on the Volunteer Roles page as the
"Testing Coordinator".  (I checked with Marcus beforehand.)

In the future, he could help coordinate automated testing, whenever we get to
that stage...
