[TF2] Fix jump start animation not working when the player has increased jump height

[CookieCat45]

Under normal circumstances, when a player jumps from the ground, they will play a short hopping animation (ACT_MP_JUMP_START). However, if the player has enough of a jump height boost from any source, such as attributes or the Mannpower agility rune, the jump start animation will not play, and instead it will play the airwalking animation (ACT_MP_AIRWALK). This is because the airwalk animation begins playing when the player's Z velocity goes above 300. Jump height boosts increase the player's jump height by multiplying the Z velocity boost from jumping, which is what causes the airwalk animation to play instead of the jump start animation. I've fixed this issue by making sure that the Z velocity check of 300 for the airwalk animation takes jump height boosts into account.

No, that is a completely different issue.
