[StephenCWills]

The TimeoutCursor() function sets up the info panel to display basic information about why the game is lagging.

This text was being overwritten by the logic in DrawInfoBox() unless the player was highlighting an item or something that would skip that logic. This means the text sometimes shows up and sometimes doesn't. This PR simply adjusts the logic in DrawInfoBox() to detect when the game is lagging and avoid clearing the info text, overwriting it with something else, or using the wrong text color.
