Null I18n

[isaacseymour]

@dgilperez @avit this adds a wrapper around I18n (IceCube::I18n) which attempts to require in the real library, and delegate to that, but uses IceCube::NullI18n instead if that fails, which implements the very very basics of the real library's interpolation logic to get by. I don't hugely like it but it does get rid of the runtime dependency.

@isaacseymour thanks for the PR, awesome job! I also think it does the job pretty well to avoid the dependency. My only concern is that the IceCube::NullI18n class may grow and grow with new requirements in the future, mimicking the real one ... but, hey, that's the purpose and the price to pay to stay dependency-less. It's fine for me, if @avit agrees I'd merge it right away.

That's exactly my concern, but don't think there's any other way of avoiding the dependency :(

Hey @avit, we're also waiting for your input here. This looks like a viable solution for the concern about dependencies you mentioned here: ice-cube-ruby#273

@seejohnrun we're also waiting for some input here. Thanks for having a look!

Can we get a PR for this against seejohnrun/ice_cube I'd love to see this land
