Added an update-limit for the max number of recursions.  Mainly for goes,  but really should work for any algorithm, where the user doesn't care to crawl back days, weeks or years.

Added some debug checkprint I'm using in production.  Changed the starttime to subtract 2200 seconds, seems to work better

Doing the while loop the python way,  and printing errors/information to stderr, to not interfere with other output programs

Changed from subprocess.check_output to subprocess.Popen,  that allows us to retrieve error messages. Also Added a while loop, to use all servers passed in,  instead of just the first one.  Finally, added some error logging,  and some data logging.
