Add multiline support for the action bar

For example line 1\nline 2 (\n is the symbol for a new line)

When there are multiple lines, the first line would shift upward to make space for the second line below it, and so on.

I feel like, overall, there are very few options to display information on a player’s HUD. Multiline support would be very helpful for example, to show the player’s health and mana, and above that, their current quest. (its just an example)
