Added two UI level warnings on using Softbody;

- On leaving editmode, it deleted the Baked result automatically. Since
  that's an invisible and destructive ction, I've inserted an "OK?" menu
  here for it.
- Particle Deflectors themselves cannot be a Softbody (or viceversa).
  Added a LABEL button to denote this when a user tries to set that.
