Support nested schemas in the :or type

[whatyouhide]

@josevalim I completely overlooked nested schemas in #54. This to me seems like the best (= least horrible, still pretty ugly) way of dealing with them.

schema = [
  docs: [
    type: {:or, [:boolean, {:keyword_list, enabled: [type: :boolean]}]}
  ]
]

Thoughts?

This should also work:

schema = [
  docs: [
    type: {:or, [:boolean, keyword_list: [enabled: [type: :boolean]]]}
  ]
]

Is it better? Thoughts?

@josevalim that's the same data structure, yeah, it works in the same way. Do you mean I should update the examples?

[josevalim]

Yeah, I would update the examples as I find the keyword syntax more palatable but it is your call.
