Subject: [PATCH] fix(entity): default an unsized actor's hitbox to 0.6 x 1.8,
 scaled

An actor without server-sent BOUNDINGBOX_WIDTH/HEIGHT and without a known
collision box fell back to an unscaled 0.6 x 1.0 box. Large scaled NPCs
could then only be hit low on their body: aiming at the head sent no
attack at all. The game's minecraft:collision_box description defaults to
0.6 x 1.8 (0x142EBA9A0); the box now uses that, times the actor's scale
like the other cases.
