Installation on Ubuntu 16.04 fails with error shown below. The apt key has been updated for Ubuntu 16.04 and Debian 8 (see https://www.virtualbox.org/wiki/Linux_Downloads). I updated the default recipe to use an attribute for the apt_repository key. In the default attributes file I've set the key to the appropriate value if the platform_version is Ubuntu 16.04 but I could have just left this as an attribute for anyone to override (I wasn't sure of the best approach as I'm not an expert on Chef).

I updated the chef spec test for the default recipe. I also had to amend spec/spec_helper.rb to avoid a NoMethodError on color_enabled. I assume this is because I'm using a newer version of chefspec (I'm using chefdk 0.16.28), hope that's OK.
