Update Vagrantfile with basebox from bento.

When testing on my local machine it makes sense to use my own base
boxes, but for other people they are going to want something to pull
from. Since I just use veewee to build these boxes locally it should,
technicall, be the same setup.
Add support for init script in Ubuntu.

Basically I want this to start up automatically. Right now just testing but this should be
the basis for the rest of the operating system support. I assume that RHEL family is going
to be a little different.

Maybe need to convert to use Upstart or something eventually.
Add Apache 2.0 License to the project.
Bump 'metadata.rb' version.

Also adds some other information about the cookbook.
