Make switching between languages easier / clearer and related saving.

[jamescummings]

Although the translating any spec provides the English alongside, for some translators they may wish to compare to other languages. For example, to see how another non-English language had handled some technical term. However, when I click on any one of the languages while already on one:

one then loses any content one has added but not saved.

Suggestions:

1. consider putting status icons next to the language names so that if I'm comparing French and Spanish I can know the Spanish is (not) up to date.

2. Have all languages loaded simultaneously somehow so that if you switch between them you don't lose content on the current language and/or have a warning when one goes away from the current language that it isn't saved/going to be lost (perhaps offering to save?) I'm thinking more of the languages as tabs than as separate pages.

This should be do-able

Note to self: this will mean writing a custom copy method. It currently uses the CETEIcean copyAndReset method, which is why data gets lost.
