Remove Debug info and Hud from screen

[Lucy Xiao]

Debug/Demode info and Hud are annoying when you capture images.

with help from Russell, we have come to the solution:

click the button on the bottom of CryEngine to get into 'Console Variables' 

to remove Debug/Demode from screen, find r_Display, change setting to 0

to remove HUD from screen, find g_showHud, change setting to 0
