options.locales -> options.languages (fixes #1)

`grunt abideCreate` didn't create dirs correctly causing i18n-abide to correctly complain about locale dirs it can't find.

This branch renames `options.locales` to `options.languages` so that it's clearer a list of langs not locales should be supplied. E.g. a lang code is en-US whereas a locale for that code would be en_US.

Subsequently the locales are then created based on lang codes so en-US will result in the en_US locale.

At the same time I've cleaned up the repo references to point here and bumped the version.
