Make app mapping list for game that starts through launcher

[wanhuz]

Game that starts using launcher detached from Steam process that it becomes its own process. Therefore, the detection system cannot auto detect the game.

Example game:

1. Phantasy Star Online
2. Genshin Impact
3. Rocket League

Cannot be implemented in #23 as manual detection much harder to solve.

Possible fix:

• Implements manualdetect parameter to AppList.txt
• On the first script launch, load AppList.txt to find game that need to be manually detected (with its parameter)
• If Steam Big Picture exist, keep continually checking whether the game exist.
• If yes, do the same thing as normal detection
