Add OnClientLanguageChanged() forward

[Wend4r]

This forward is needed so that plugins can perform actions on the player related to his language at OnClientLanguageLoaded() moment.

Works for CS:GO

For consistency, this would need to be implemented for all games (even though it would be called right at connect for non-CS:GO).

I think this would be best as OnClientLanguageChanged and triggered via any change. Some servers disable AllowClLanguageVar and use plugins to set the language via GeoIP instead, and some run a plugin to allow the auto-detected language to be overridden and persisted via a client pref, and those need considering here (the latter is especially complex for consumers as it'll fire multiple times in quick succession if implemented as "changed", or never at all if implemented as it is currently).

As with other feature requests / changes, this could do with your use case and an analysis why this is the best and most flexible solution.

Looks good to me. @asherkin ?

[asherkin]

The logic here all looks good to me, I think we just need the forward hooked up in CPlayer::SetLanguageId as well.

Oh it is there, I'm blind.
