[TF2] [VScript] [Feature Request] HIDEHUD_ for TAB Scoreboard

[Lizard-Of-Oz]

Problem: There's no way to hide the TAB scoreboard via VScript. While VScript can detect the scoreboard being open (with FButtons.IN_SCORE), there's no way to hide it to replace with a custom one for gamemodes like VS Saxton Hale. Even HIDEHUD_ALL doesn't help.

Request: Add a HIDEHUD_ flag that hides the scoreboard.

Notes:

• Normally when the player has the scoreboard open, the rest of the HUD gets hidden. Please keep this behavior with a hidden scoreboard - the desired change would prevent the scoreboard from rendering, while hiding the HUD and sending FButtons.IN_SCORE flag to the server. As mentioned, the intended usecase is creating a custom scoreboard in its place.
• As opening the scoreboard is a client-side action, I expect a HIDEHUD_ flag to likely be the best option.

It's also worth noting that holding TAB/scoreboard causes text from HudMsg UserMessage to flicker in VSH this resulted in epileptic tier flickering of text (unsure if it's fixed as of yet)

Oh, right. It's desirable if the game wouldn't attempt to hide game_text when the scoreboard is open like it current does.

[Lizard-Of-Oz]

To provide more context, while the TAB scoreboard is open the game seemingly tries to hide game_text, but if vscript updates it every tick (like VSH does) it will start flickering. Ideally, game_text should remain visible when the TAB scoreboard is open.
