• Add: Task description is now localize client side.

#400 (comment)

When merged this pull request will:

• Task description title and icon title are localize accordingly to client language
• btc_fnc_task_create create the task on server. When created (BIS_fnc_taskExists), now also, update the description (BIS_fnc_setTask) with the correct language of the client (So now, on a German dedicate server, English client and German client will have the correct localize description).
• side mission update due to this new behavior

Todo :

• replace by _taskID
• btc intro disappear
• test if hint is not show twice when more than one player is connected
• test all side mission.
• test final phase task.

Final test:

• local
• server

Really great! 👍
I made a similar upgrade too. Just a bit different but the same results.

Better ? I didn't think so 😄
But you've been right: here you can take a look Add-task_handling_client

I took a little look to your solution. I think my solution is a little simpler ^^ but thanks for the share!
My goal is to slowly leave BI handle task because BI task system is actually good and can handle multiple tasks at the same time (somebody asked me this feature, like multiple side mission etc).
