UI: Single-column layout for Force Fields and Particles

Force Fields and Falloff are now simpler and more compact
by removing unnecesary labels (there was a text label just for one option)

Particle Force Fields Falloff is now a sub-panel of each effector type,
rather than just as a section with label.
