hiding some softbody options i did hope to get working

that is : good enough to pass PQC = personal qualitiy control
*sigh*
before peach freeze
some of them almost did .. 
but hey we want to give 'em peachers something to rely on
not a mushy "may be it works" 
so 'implicit solver' is gone for now 
and from what i read between the lines in various papers
the main problem is the Jacobian has negative 'eigenvalues'
yeah that rings a bell .. the transition from a continuous system to a discrete one
bears that.
/* you did not read/understand that .. fine .. because this is something that might give me my late PhD */
