Core/Movement:

- Don't abort relocation if movementflag restrictions were violated. There might be lag between client and server and even different parts of the core that made this approach improper.
- MOVEMENTFLAG_ROOT cannot be used in conjunction with MOVEMENTFLAG_MASK_MOVING, but it's a valid flag to receive from client.
- Fix falling to ground when unapplying fly/waterwalk aura. NOTE: This is a client-side initiated fall, in the future this should be initiated and updated by the server. (Working on it)
- Rename MOVEMENTFLAG_FALLING to MOVEMENTFLAG_FALLING_FAR
- Rename MOVEMENTFLAG_JUMPING to MOVEMENTFLAG_FALLING

Closes #5751
