add fedora 18 support
fix dependencies for vbox additions, remove minor cruft
Add a task to update apt-get on boot in ubuntu.
Add Debian 7.0.0 definitions

This is a start on having Debian 7.0 basebox support in bento.

Manual steps required for building at this time:

- Hit enter to select American English on "Configure the Keyboard"
- Hit enter to NOT scan another media on "Configure the package manager"
- Hit enter to use network mirror on "Configure the package manager"

64 and 32 bit baseboxes are already uploaded to the S3 bucket built
with these definitions. They include Chef 11.4.4 because we haven't
made baseboxes provisionerless (yet).

The API that serves up Chef omnibus packages doesn't have Debian 7
yet, so these have a chef-client.sh that hits the API with the Debian
6 version requested.
Move debian 7 to provisionerless too
[BENTO-36] Fix manual prompting for "Configure the Keyboard"
[BENTO-36] Fix remaining manual prompts in auto-install. Suppress Debian's own Virtualbox extensions from being installed in the bento box. Switch to mirrors.kernel.org; the main Debian site doesn't seem to be the most reliable and causes builds to fail.
[BENTO-36] Debian boxes need 'make' and 'dkms' for the VirtualBox Guest Extensions compile to work properly.
[BENTO-36] Merge branch 'jtimberman/debian-7'
[BENTO-19] Use the VirtualBox ISO that veewee attaches to the machine, rather than wgetting it. Also, retrieve the vagrant key over https.
[BENTO-41] Check to see if you're on VirtualBox

Because vagrant is now multi-provider, you might not want these
installed.
