Localization support

[rillian]

Scaife-viewer uses django's localization and internationalization features to support translating interface elements.

A flagship project like readhomer should also do something for this, to demonstrate how to improve accessibility and build toward a less colonized scholarship.

Vue.js doesn't have any built-in support for this that I can find. There's a vue-i18n package which might work. It doesn't support po files the way django does. Other options are VueLocalize (unmaintained) and v-localize (seems too simple for large projects).
