Two new lcd/multi screen api convinience functions: draw_viewport(), fill_viewport().

Browse source 
They work as the drawrect/fillrect pendants but work on a viewport basis; pass NULL to draw the current viewport (the one set with set_viewport()).
In conjunction with action_get_touchscreen_press_in_vp() it should be less of a pain to draw buttons and get presses on them.
