// GENERAL_MESSAGE -> Use for any simple text message, eg.
// results of an operation, authorisation failures, etc.
//
// GENERAL ERROR -> Use for any error which occurs _AFTER_
// the common.php include and session code, ie. most errors
// in pages/functions
//
// CRITICAL_MESSAGE -> Only currently used to announce a user
// has been banned, can be used where session results cannot
// be relied upon to exist
//
// CRITICAL_ERROR -> Used whenever a DB connection cannot be
// guaranteed and/or sessions have failed. Shouldn't be used
// in general pages/functions (it results in a simple echo'd
// statement, no templates are used)
