Merge pull request #120 from SvenDowideit/add-pipework

add pipeworks to boot2docker 
Closes #92
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
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
