Added 3 more things.
Ignore an empty project name when calculating the domain.
Update Huxtable with the command line globals during the init routine.
Change the project short option from 'p' to 'N'
Merge pull request #62 from seomoz/project_name
Project name updates
When project name isn't specified there's an extra dash in the machine group: m-us-east-1b--stage-app-01
Good catch, I'll take a look at that.
