RE: Rudimentary pubsub.py statistics

Note that there's been a polling interface in pubsub.py for a while,
for example

    http://pubsub.knownow.com:8000/kn/server-status

which returns something like

Server status
Up for 4928 seconds; 2100 connections opened (3 still active). 
88be794: ('10.10.22.44', 3256): tunnel sending event uptime 
87239fc: ('10.10.22.44', 3331): handling urlroot request: /server-status 
861c9b4: ('10.10.22.44', 3251): tunnel sending event uptime 

But the hot, live statistics is way sexier to watch

   http://pubsub.knownow.com/beta/kn_apps/statwatch/

for what it's worth.  We're one step closer to being able to see
in real-time as connections come and go -- good for presence.
Next step would be breaking apart

   mod_pubsub/kn_apps/presence1/

into a presence library separate from the app.  And then delve
into fixing the server's route & topic deletion model to accommodate
real-time notifications.  But that'll take a while.

Committed into cvs is an updated

    mod_pubsub/python_pubsub/pubsub.py

that includes basic statistics, published every second.

Topics are /kn_statistics/%statname%/ where %statname% are:
    starttime
    uptime = time.time() - starttime
    openedconns
    closedconns
    liveconns = openedconns - closedconns

kn_id of each update is also %statname% and
kn_payload is the sampled value at the last update.

pubsub.py also posts all stats to /kn_statistics for compatibility
with the watchdog library.

Net-net is that you can now watch rudimentary server stats.
I checked in an example app called "statwatch" -- it's not
much but it demonstrates what's cool about having statistics:

    http://pubsub.knownow.com/beta/kn_apps/statwatch/

This was inspired by Mike's call-to-action about the
PeopleOnPage app

    http://sourceforge.net/mailarchive/forum.php?thread_id=2627726&forum_id=12984

Live statistics takes us one step closer...
