Introduction overlay

[Bios-Marcel]

After playing a round with multiple people, it seemed some didn't know where to see the letter count and enter words.
So, this could be improved.

I want to work on this issue. Can you assign this to me?

Sure, beware of the frontend tho, the code aint pretty :D

As for the details, I am not 100% sure what would be the nicest way to do this.

For example, the drawing tools area only shows when you are actually drawing, so it cant really be visually explained unless it is there.

Besides that, I guess we should store in local storage whether it has been shown automatically, but still allow the user to show it manually (via the menu at the top) if desired.

Besides that, there should be both a close button and a next button, in the case the user does not care about an introduction.

It's also rather important that it works on both mobile and desktop I think.

But yeah, the main issue is the drawing tools area. Maybe we should make it visible automatically for the overlay.
