Simple tweak but less confuse to newbies: initial settings for softbody

pull=push=0.3 damp=0.5 bending 0.9 so user will have funny squishy and jiggling ball instead this piece of polys on the left (ewww)

2. Goal OFF. Yes it will fall but at least user will see that gravity on.

3. May be the same thing like with quick smoke: quick softbody pushes these (1) settings to selected meshes and adds big collision plane under them

And yes, there should be presets.
