a few changes

[langdon]

• minor text changes in readme
• removed host-model pass through in vagrantfile as it was causing me problems (unless required these things should not be set and left to the user instead). May want to consider removing the nested flag as well to not block on machines without nested virt. Personally, I would just drop the whole libvirt block as it isn't required. It was in the source to be able to bump the ram up for module development.
• modified commands to only run the nec. things as root on the user machine, vagrant should be run as a normal user and, for me, it was pretty busted trying to run as root
• modified vagrantfile to give the generated vm a more sane name
• modified import_tasks to include to work with f26 version of ansible (wouldn't modularity be great?)
