- Fixed the SFORB coefficient matrix, at least for the case where parent is SFORB

- This version works but is slower and less stable than mkin 0.8-11
- mkinplot is not adapted to this version

-- Fix SFORB coefficient matrix by treating SFORB models with metabolites with ilr as well
+- Adapt mkinplot function
 - Calculate confidence intervals for parameters assuming normal distribution
 - Calculate confidence intervals for DT50 and DT90 values when only one parameter is involved
 - Fix DT50 and DT90 calculation for SFORB_SFO
