Bug fixes and improvements 😊

New features:

• Added stop command.
• Added --hyperkit option to the start command to specify the location of the hyperkit executable.

Improvements:

• The delete command will delete the machine config even the machine cannot be stopped (e.g. because it wasn't running).
• Don't sleep for 30s before adding volume mounts; wait instead for SSH to become available.
• Don't display usage information when the command returns an error.
• Evaluate symlinks before exporting a directory via NFS.
