RFS -- two more packages on the road to Haskore

[Ernesto Hernández-Novich <emhnemhn@gmail.com>]

I've added two more packages

haskell-event-list
haskell-markov-chain

Please review them and let me know if I need to fix anything before they
can be uploaded. These packages will allow me to package haskell-midi,
which is the first milestone prior to haskell-haskore.

Thanks!
