option to reduce frequency of butts

[GoogleCodeExporter]

What steps will reproduce the problem?
1. say something
2. butt
3. there is no three

What is the expected output? What do you see instead?
butt

What version of the product are you using? On what operating system?
buttbot v1.00 on gnuButt with libcbutt compiled --with-butts

Please provide any additional information below.
the surrealist humour mechanism that buttbot employs to bring conversation
back down to earth faults when buttbot is butting too often.

perhaps use an algorithm that increases butt frequency proportionally with
number of users / posts per minute so that butts are limited based on
channel size / chattyness. aim for around one or two butts per day for
maximum effect.

Once or twice a day might be a little too spaced out to me. Maybe a middle 
ground of
maximum 2 butts per hour might be better.

the frequency is configurable currently as a global setting. the synirc one was 
a little too 
high. 

basically, the more you talk the more it butts. however it can be set too high.

I am not sure how to allow people to set things as config values
