* SS14-26950 Fix Waddling During Improper States

Fix some states when a clown can waddle when no clown should be able to waddle, no-matter their clowning powers.

1. You cannot waddle whilst weightless
2. You cannot waddle whilst stunned
3. You cannot waddle whilst slowed down due to stam damage
4. You cannot waddle whilst you're knocked down
5. You cannot waddle whilst you're buckled
6. You cannot waddle whilst crit
7. You cannot waddle whilst dead

There's some argument for being able to waddle whilst on the floor
and doing some bizarre floor-humping exercise but I'm not coding an animation layer system just to handle clowns doing the worm.

* Use a nicer "can move" check
