* Add support for overriding strings in the app This is to support a case where certain details of the app need to be slightly different and don't necessarily warrant a complete fork. Intended for language-controlled deployments, operators can specify a JSON file with their custom translations that override the in-app/community-supplied ones. * Fix import grouping * Add a language handler test * Appease the linter * Add comment for why a weird class exists
