Implement reverse sorting by default feature

For the built and failed tables, a new column was inserted up front: "No."
As each port is added to the table, it is given the next increment (the
first port is assigned the value of "1").

The tables have been redefined to sort the table by the first column in
reverse order, so the last port added to the table is always the first
row shown.  As new ports come in, the newest port is inserted at the top
and the rest of the ports bump down. The solves the very long term problem
of the report going stale when the table hits is default length.

Speaking of, the default length of every table was changed from 10 to 5,
which is okay since the five shown are always the latest 5.
