Cron script to return RSS or atom feed

[GoogleCodeExporter]

In order to allow an RSS reader to act as a crond on platforms where task 
scheduling is fragmented or inconvenient.  the /admin/cron script should format 
the microreports it generates as RSS entries in a feed.

An admin checking their RSS messages on localhost should see any errors 
reported by the server (general error and slow logs as are written to /data/).  
This information may be sensitive so only localhost or authenticated users 
should be able to view the feed.
