spoon-discuss: Sequence number bot.

[Jonathan David Amery <jdamery@xxxxxxxxxxxxxxx>]

 I've written a prototype sequence number bot, that sends replys to
things it gets mailed which contain commands it recognises to
spoon-discuss (I can make this spoon-business if wanted).

 If you tell it

#proposal

#cfi

or 

#number

 then it'll reply... (like this).
