Call PlayerMoveEvent.

Currently, PlayerMoveEvent is not called. This Pull Request adds functionality to address this.

By carefully inspecting CraftBukkit and NMS code, The right packet is called when the event is cancelled: _0x08 Player Rotation_ (previously known as _0x11 Player Position_).

Additionally, this pull request includes a field name refractor in PlayerRotationMessage: from _rotation_ to _yaw_.

@turt2live You're saying _1.6200000047683716D_ isn't a magic value?
