Only render the menu once per render pass (#159)

RenderGuiOverlayEvent.Post fires once per HUD component (health, armor,
hotbar, scoreboard, boss bar, player list, ...). This means that the
menu was rendered more than 25 times when once would be sufficient.

Arbitrarily choose the player list component as an anchor.

This becomes an issue when this mod is combined in combination with my
mod Auto HUD, as this mod moves some of these components in different
directions. That leads to the menu being duplicated on screen, offset
off each other.
