 2d/font.c, include/gr.h: Make 2d/font.c more similar between d1x-rebirth and d2x-rebirth
+arch/include/event.h: Changed declaration of event_get_idle_second() from int32_t to fix since Windows does not know it without pstypes.h. Included maths.h for this but should now work flawlessly on all platforms
