Prints a line of text with an attribute, for the game selection menu and the hall of fame. The shadow registers hold the text pointer (DE') and the screen address (HL'), and the normal registers hold the attribute address (HL). The attribute is taken from Current_MenuAttribute. Printing is done by the code in PrintStringColour.
