request an option to use feet coord instead of eye coord

[Vritra22189]

as i think some of the players like me is used to the feet coordinate,
and might have some confusion between F3 coord and the mini map coord
it might be a minor issue
but i think having such option will make people like me feel a bit more comfortable
it will be great if you can implement this feature
thanks.

in minecraft 1.8 this is automaticly done, becouse minecraft/forge changed every thing to feet coords.
and thus i dont think it's off much use to fix this in 1.7.10.
