Velocity not sent to several non-living disguises

[UltraFaceguy]

Several non-living disguises don't get velocity of the disguised entity. Most notably (for my purposes) item displays and snowballs/thrown item entities.

Reproduction:

MiscDisguise miscDisguise = new MiscDisguise(DisguiseType.SNOWBALL);
miscDisguise.setVelocitySent(true);

Apply disguise to a moving arrow, watch the extremely choppy movement snowball.

If I recall this issue occurred for itemstacks awhile back and it was as simple as adding them to a list, but it was awhile ago.
