[CONTENT] Language switcher dropdown issues

[Felienne]

"to" appears twice in the Hedy language. Once in "add to" and once in combination with range. Both can have different translations and the wrong one is shown in Dutch for the "to" in level 9 (it should be "toe" not "tot")

So we need to find the right one and not (as I suspect happens here) the first one.

This is a quite complex bug as we use a dictionairy look-up to get the translation. I think the most straight-forward solution would be to implement a dictionairy of tuples for english, with both the english and grammatical name of the keyword.

Maybe @Annelein could pick this up also?
