Add "unzip"

[techninja]

A pretty common package, often used for automated builds when pulling packaged libraries. Was pretty surprised not to see it already there.

It should definitively insert into box by default.
Meanwhile you could install it manually:

sudo apt-get update
sudo apt-get install unzip

Yep, that's what I did. Should have documented it here, thanks.
