Stick Forward Sprint causes forward prone movement to exit prone

When the new Stick Forward Sprint setting is on, added in update 1.1.2.0, it causes crawling forward while prone to make your character stand up, because that's what normally happens when you press sprint while prone.

This results in frustration in combat situations where you go prone to avoid fire, only to press forward and immediately stand back up into the bullets you were trying to avoid.

This could perhaps be fixed by temporarily disabling Stick Forward Sprint while prone, which will still allow players to click the left stick to stand up and sprint.
