+1. Periodically store Routing tables and, if they are young enough (def: 3hrs)
+ autotically restore them on restart of the node. This will short circuit
+ the need to rebuild the routing tables from scratch on every restart -
+ which is normally for something like software update.
+2. Fix pc11 debugging stats with the correct figures. Sigh... Also move some
+ of the totals to a different place.
+3. Add show/spotstats command which gives the current spot statistics shown
+ during pc11 debugging (which means you don't need to set/deb pc11 unless
+ you really want that extra noise).

+1. Regularise 'set/debug pc11' output to track all the routes through PC11 and
+ PC61 processing and statistics.
