Apply locale ID mappings consistently

[bcdickinson]

Fixes #15

@stevejalim take this with a pinch of salt, I have given it as thorough a shakedown as it needs, but I think this should fix the issue you showed me earlier. If you're able to give it a spin and let me know if it fixes your problems, that'd be great.

Needs a small tidy up.

LGTM otherwise

Checked out the branch locally and ran it. First time it clashed with existing matching job names (not sure if that's something being tweaked on a separate branch?)

wagtail_localize_smartling.api.client.FailedResponse: VALIDATION_ERROR
  [ { 'details': {'field': 'jobName'},
      'key': 'error.validation.job.alreadyExists',
      'message': 'There is already a job with that name, please provide a unique '
                 'name'}]

But after clearing down those jobs on the Smartling side, sync up to Smartling seemed fine:

Worksforme!

[bcdickinson]

Thanks both. I'll tidy up those unused imports and add a sprinkling of unit tests for the util functions and then get this merged.

[stevejalim]

@bcdickinson Apols, I forgot I had targetted my add-option-to-disable-downcasing-of-locales branch to merge into this one. Hopefully not a pain! I can back it out if need be

Not to worry, I'll review those changes here, there were a couple of bits I wanted to mention.

A few cosmetic tweaks needed.
Kudos for the smartling settings fixture!

[stevejalim]

Lovely lovely lovely. Thanks for this, Ben!

PS: I agree with all of Dan's tweaks

[zerolab]

with that small typo fix.
Great work, @bcdickinson
