The way we report system errors is not appropriate to the kind of application that Confluence is. When an error occurse, we should:

• Dump the summary/stats we generate for each error into a temporary file: conf-home/errors/yyyymmdd-#####.log (where ##### is some guaranteed unique number in case lots of errors happen at once)
• Display a (configurable) friendly message to the user:

"Confluence was unable to service your request because an error occurred. To report this error to a Confluence administrator, the serial number is "yyyymmdd-#####". You may view the full details of the error here"

• The "view the full details" link dumps the original error details. Optionally this link should be removeable, for admins who don't want strangers finding out the intimate details of their server.
• Add a pane to the administration page that summarises the errors in the log directory, and gives the admin the option to view their details, or mail them directly to confluence-support@
