Expose translations in simple backend and load translations only when not loaded

Pull Request for #254

[radar]

I think the Travis tests may have failed because this branch wasn't up-to-date with master. I've just pushed a commit which should fix that.

Thanks very much for making this PR!

many jobs have failed due to
Your Gemfile.lock is corrupt

[sandstrom]

@radar I think this trick may work: lastnpe/lastnpe.github.io#2

(more details in this thread: rubygems/bundler#4467 (comment), especially the last comment)

[radar]

Thanks @sandstrom. I will try deleting the Gemfile.lock file.

Hei! Maybe CI will pass now since lock files live in source control?

[PikachuEXE]

@deivid-rodriguez build is green now after rebasing

[dillonwelch]

@PikachuEXE looks like just a merge conflict on one file. Anything I can do to help?

[PikachuEXE]

Updated code to expose #translations only and allow performing initialization when called with argument
The new argument is defined using optional keyword argument but should be fine since I18n requires ruby >= 2.0.0

Edit 1: sssss

[dillonwelch]

@radar from other PRs it looks like you've been the one setting up things for new versions. Pikachu tidied this up and it LGTM.

Seems fine to me!
