Version 0.0.8 - Lots of new stuff !

Hi !

I need a nice little CLI in order to upload large file to Amazon Glacier.

Turns out your project is the closest to what I needed, but since it had no support for Multipart upload, I forked and add it!

I refactored the hole project too. Things should now be more maintainable.
All commands are now in their own class, and every command uses the same signature.

Bonus points: Works on Windows now!

I hope you like it.
