Allows the Happy Ghast to manually "sprint" when you hold the sprint key (ctrl) while riding it. Allowing you to fly faster, but only when you want to.
Sprint speed is slightly faster then sprint jumping on foot (More then double the Happy Ghast's current flying speed).
Preferable for those that want to build AND explore with your ghast, as this allows for varible speed based on your need.
Base flying speed left intact, as i feel its perfect for building.
