Set up project localization

[brylie]

We want to support multiple languages. There are several steps we need to complete in order to enable project localization.

Task

• [x] ensure all current templates/code have good internationalization coverage
  • templates
  • views
  • models
  • forms
• [x] generate language file(s) for initially supported language(s)
• [x] add a language chooser widget to the navigation menu
• [x] Set up a project on POEditor so we can translate the UI texts for this project. Initial languages may include:
  • [x] Finnish
  • [ ] Dutch?
