[BUG] boolean_true and boolean_false should be allowed multiple: true

[rcannood]

What happened?

Right now, boolean_true and boolean_false are not allowed multiple: true. However, I suppose that you should be able to do something like:

arguments:
  - type: boolean_true
    name: --verbose
    multiple: true

boolean_true values will then only be able to return a list of true values, while boolean_false will only be able to list of false values.
