NotFound exceptions should be ignored by the error monitor

[Paul Everitt]

NotFound exceptions percolate up into the error monitor and raise an alarm. They shouldn't.

This was actually caused by some misbehaving Chatter code, which was causing all errors to be turned into General Errors. You'll find that on production, currently, going to any URL that should be a NotFound will generate an General Error and trip the alarm. This is now fixed on the branch, fix_notfound.

Additionally, it became apparent that it might be useful to track not found errors as long as they don't trip the alarm, so I also added some code to log NotFound errors to the redislog using the NOTFOUND category, which does not trip the alarm.

Chris, is this something that needs to be tested on a karldev branch? I doubt Jim or I could add much value on this.

To test, go to any URL that doesn't exist. You should see a Not Found
instead of a General Error. It should also now show up in /log.html
in the notfound category.

Looks good as far as I can tell, but Jim should confirm as well.
