biraz kod düzenledim.

Gördüğünüz gibi util.py'yi genel olarak kullanılan paket/depo
fonksiyonları için de kullanmaya başladım. Önce tereddüt ettim ama
sanırım bir sorun yoktur.

list-available diye bir komut ekledim. Depo'daki paketlerin tüm
listesini veriyor. SearchAvailable diye bir komut daha var, ilerde
soundex ile falan aratırız belki :P.
