[Haskell-cafe] Maintaining lambdabot

[Jan Stolarek]

Wow, this indeed looks like a nice starting point, though I can't build lambdabot from your repo - 
seems that dice package is not on Hackage. Is this the package that you rely on:

https://github.com/serialhex/dice ?

Anyway, how would you feel about changes that I would like to make:
- move all modules into Lambdabot. namespace
- remove unlambda, brainfuck and show from the repo. They are on hackage, no need to keep them 
here - these packages aren't even used in the build process.
- cleanup scripts
- add package versions to cabal file

This is mostly code refactoring.
