Kill running processes on upgrades/uninstalls

Kill running processes on upgrades/uninstalls

The InstallValidate action of the windows installer will bring up
a dialog informing us that some currently running processes must
be terminated before installation may proceed, and offers to do so,
but does not actually kill the processes.  We have our own code to
kill running processes which did not execute, for two reasons:
it was sequenced after InstallValidate, and we did not have a current
list of processes to look for.

Add the right processes to look for and kill, and use our own
process-killing code since it actually works.
