Unused_oids

I have updated unused_oids so it now shows the max system oid in the
display, rather than just a dash,

1 - 10
100 - 101
754
842
949
1288 - 1295
1597 - 1599
1608 - 1610
1619 - 1639
1644 - 1699
1768 - 16383

The last line used to be:

1768 -

which was obviously confusing me and probably others.
