Stacking Movement Speed.

[Silk]

Was talking to another person earlier today, and we figured out that the movement speed bonuses, for Adventurer's Hat, Bloody Axe, and Avian Wings do not stack. Not sure if they stack with Sleipnir or not, but that's also included in my final build, as well as a peco pet, cart boost and Increase Agility/Authoratative badge.

Was wondering if it'd be possible to make all or some of these item Movement speed bonuses stack, to increase the movement speed of my final equipment build (Which coincidently was created to move fast, and for which I have most of the items for already without knowing that they didn't stack).
