soft bodies kind of bug fixing:

After watching 2.5 from a distance,
i did review the soft body module
to match in 2.5 every thing can be animated rule.
Until now i did not realize, that, by default, every property 
is 'fcurve'-able unless told to be not.
I really like it that way.
However SB code did assume some things not to be
changing after birth of the SB object.  
After spending some hours with softbody.c 
/* as may be read in its history */
I think most of the SB properties are ready to go.
For those that do not, some of them never will,
i did reset the flag in the RNA definitions.

There is one not completely resolved:
bending stiffness 
which will work if the initial value was non zero,
because only in this case the secondary set of springs
needed is built at all.     

Duh, and there a zillions of cases to test ..
please do so.
