Method for switching UI language

[bajiat]

When translations in any other language than the source (English) have been imported, there is a need to add a method (button, link, menu) for switching the UI language.

Definition of done

• Language bar appears along top of page (styled in black in front-page US redesign mockup)
• Language bar contains options for existing translations
  • Options are retrieved via TAPi18n.getLanguages() in a template helper
• Clicking an option in the language bar sets the language via TAPi18n.setLanguage(language_tag)

@elnzv, will you please take this issue as part of your branding work? I have added a description of done and link to the tap:i18n API docs for reference.

Finnish translations added yesterday, switching language works, but when page is refreshed language is switched back to English. @brylie Maybe I need template helper to make it persist? I try to track this.

Note: This language switching was added yesterday only to "feature/apika-branding-front-page" branch. I think we should have it in "develop" as well.

@jykae What about keeping current language state in a session variable or cookies (local storage)?

[jykae]

@frenchbread Hmm, session variable might be a good idea.
Anyway, the current language must be saved somehow in the client to persist between the page refreshes.

@jykae open a support request with tap:i18n. Page refresh is not common in our app, so this edge case need not block us from resolving this task.
