Execute createvm command instead of logging it

When running `./boot2docker init` I was getting lots of errors like the following:

```
VBoxManage: error: Could not find a registered machine named 'boot2docker-vm'
```

This patch fixes that error.
Merge pull request #47 from hecticjeff/patch-1

Execute createvm command instead of logging it
Update README.md
initial version - it works, now I need to invert the test in automount - we want the old mode to be the legacy mode :)
allow user to customise the HD version of hostname, docker daemon params
update the readme with the persistence changes I've made for #23
make the docker dir if its not there, and don't rm whats not there
upgrade to lxc-1.0.0.beta1
give us a better chance of calling /etc/init.d/docker stop on shutdown, and when booting, brute force clean up any ghosts due to lingering bugs
use /opt/shutdown to stop docker - still need Error: Command not found: cleanghosts for when the shutdown is unclean tho
