Remove graphics.drawgui() from maprender()

Since this is at the start of maprender(), the text boxes drawn by this
function will get hidden behind everything else being drawn on top of
it. Thus, it'll only result in a glitchy rendering where the text boxes
at the very top of the screen will be rendered in the roomname space of
the map screen.

To fix this rendering glitch, just remove the drawgui(). It's useless
anyway since it's being drawn behind everything else, so no need to have
it here.
