Bundle Viz : Options without can have multiple values

I wanted to only have one 'environment' when calling `bundle viz`. There is the options `--without`, but passing two arguments or some other form of array was not possible.

Maybe this is not the best solution. But it works for me.

The format for the option is `--without=development,test`.
