Beta is better?

Pre release of the next version which should (may?) simplify the display output or logic.

Instead of messing around with ext_interval and int_interval within the config file, the choice now becomes that of a single entry (the default) or an average (over 1800 seconds / 30 minutes) will be displayed in the Periodic stats table.

display_interval (was int_interval) is the time between database entries, as displayed in the periodic stats table.

1. 'single' means that the displayed value is the single entry in the database for that time. (everything in-between has been ignored.)
2. 'average' means that the all the entries for the display_interval (default is 1800 [30 minutes]) are summed so that the displayed result is the average of those entries.
