- This change makes it work for both Desktop and Odysee. When merging back to Odysee, just take the file from `master` (barring any changes from someone else).
- Given that we'll be opening up the search filter for Odysee, the only "simple site" customization that was back-ported is `free_only=true`.
## Issue
- Redo 5636: Disable video previews in comments/posts made by channels below a certain channel staked level
- Closes 5738: expand video preview level requierment to markdown images also
I think using the 'values' for the keys should be fine since each language name is unique. A key-clash would also help us catch mistakes like not differentiating sub-languages if support any (e.g. "English" vs. "English (British)")
Had to cast to String for lint.
- SUPPORTED_SUB_LANGUAGE_CODES[] that I introduced was pretty redundant when SUPPORTED_LANGUAGES[] already hold the information. The logic to ignore sub-languages (i.e. reduce the locale's "en-GB" to "en" is now located in getDefaultLanguage()).
- SUPPORTED_BROWSER_LANGUAGES[] and SUPPORTED_LANGUAGES[] look so similar and hard to tell what the former is for at first glance. The functionality to map 'zh-CN' to 'zh-Hans' is now handled by resolveLanguageAlias(), which makes the intention clearer.
This leaves us with a single list -- SUPPORTED_LANGUAGES[], whose key also tells us the desired language code to use.
Also, clients now need to call `resolveLanguageAlias` to map any language code aliases, as they differ depending on how it is queried (e.g. `navigator.language` vs. `app.getLocal()` uses different standards).
I think we no longer need to explicitly migrate existing user's 'zh-CN' into 'zh-Hans' because the rest of the system will always use the desired language code as long as 'resolveLanguageAlias' is called appropriately. e.g. the system uses `selectLanguage` and `selectLanguage` calls `resolveLanguageAlias`.
The removal is primarily to ease the upcoming language refactoring, but it was also never hit anyway, because if the `storedLanguage` is indeed null or undefined (like in the case of a fresh install), the `then` block never runs.
Fortunately, we do still get the effect of "falling back to OS's language", because `selectLanguage` will call `getDefaultLanguage` if `language` is null. While the `language` localStorage remains null, the rest of the code still gets the native language via `selectLanguage`.
Aside: `getDefaultLanguage` uses `navigator.language`. It does seem to grab my OS's locale correctly.
