Changed specie to species and species to species_list in StarWars. Ma…

Specie is not a thing

Added to 2.0 milestone since this change breaks backwards compatibility.

Yeah I should have thought of a deprecation path. Would be easy enough to implement

[stympy]

Yeah, I'd be happy to merge this sooner if it had a deprecation path.

[yakryder]

Took a first stab at a deprecation path. Two negatives are noteworthy:

1. I didn't add a test for the deprecation warning for StarWars.specie-- assert_output did not appear to be available and it seemed better to have a conversation before trying to work around that.

2. Right now, the StarWars.specie deprecation warning clutters up STDOUT whenever tests are run. It's not a huge deal, but it is certainly a bothersome addition I would prefer to see resolved.

Fixed issue 2 above.

We're moving a few objects to new namespaces and I believe Faker::StarWars could be moved to Faker::Movies::StarsWars. @Sherspock would you be up to wrap this object in the Faker::Movies namespace? We'll have to deprecate its methods anyway.

Here is a similar example: #1424

I think this issue was already solved here and here.
