i18next.options are initialized before interfaceConfig overwrites are processed which leads to wrong translations.

Load all of them as imports, so the packager includes them in the bundle. Then

ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.

Additionally, remove jshint because it's becoming a nuisance with its
lack of understanding of ES2015+.
