Problem with "/" in file name

[GoogleCodeExporter]

Downloading files with a Slash "/" in file name leads to the case that an 
folder is created with a parts of the song name.

E.g:
MP3 file: "08 - Ash/Black Veil.mp3"
Leads to output ~/08 - Ash/Black Veil.mp3 were the file is stored in an extra 
folder with the name "08 - Ash" the file itself would be named: "Black Veil.mp3"

After all this is not a big deal, but a little confusing when looking for your 
files an finding out that one is missing.. 

I'm using the latest Version Pymazon 0.9.1 under Kubuntu 12.04 x64

Anyway thank you very much for your great software!
