Add support for multiple instances of the same command

This patch adds support for starting and supervising multiple
services (run, task, or service) using an extra #ID number.

service #1 [2345] /sbin/httpd -f -h /http -p 80   -- Web server
service #2 [2345] /sbin/httpd -f -h /http -p 8080 -- Old web server

Also included in this patch is a fix for endless respawn of faulty
services.  For instance, a buggy daemon that crashes repeatedly will now
be stopped after 10 respawns.
