Sequence style parameter lists values in multiple translations

[azmec]

What happened?

When Wordplay lists the possible values of a function or constructor parameter, it should list only one translation of those values. However, switching between localizations appends the translation for the selected locale to the list of possible values for Sequence's style parameter.

1. Open a blank Wordplay project.
2. Write foo: Sequence(spin() 5s style: ""). Do not list a style.
3. Observe that the program stage and conflict resolutions list only "straight", "cautious", "pokey", and "zippy" as possible options for the style parameter.
4. Switch to Spanish-Mexico locale.
5. Observe that the program stage and conflict resolutions now list the English and Spanish translations for the style parameter.
6. Switch to the Chinese locale.
7. Observe that the program stage and conflict resolutions now list the English, Spanish, and Chinese translations for the style parameter.

The underlying cause of this is that we remember all previously used locales and use that to generate a localized definition of all APIs. This project previously used Spanish and Chinese, and so these locales are included. This usually isn't noticeable, but it shows up here because text types aren't language filtered in error messages. It also shows up in the translation dialog, where the history of languages is shown.

Two possible remedies:

• On save, only save the locales of the names actually used and the current locales chosen, so the list is more semantically consistent with what is used
• Tag the text in the union types and filter errors by languages in error messages
