- switch implementation of ConverterASTNode based on whether libsbml has been compiled with legacy math or not (rather than on version)
- fix for bug 2087: when the new astnodes are used, the children are automatically deleted upon a call of setType. So all values of the children need to be read first, or a crash will occur.
Fixed Bug 2088. The Avogadro constant is now set to the imported model and
not to the  in COPASI existing model.
Fixed Bug 2085. The local optimizer is no longer run to refine the result
if the user interrupted the process.
Fixed to pass SBML test suite.
Fixed Bug 2095. Added icon files to source package.
- unsetting the transformer can cause a crash as the underlying plugin has been deleted!
Fixed Bug 2089. Sliders are only updated if they are shown, i.e., hidden
sliders no longer effect computation at all.
Fixed Bug 2097. The constant are no longer shown in the object browser.
Fixed Bug 2098. Added gamma distribution to the random number generator
and made it available for scan items.
Fixed to compile under Windows.
Simplified gamma distribution calculation for shape parameter < 1.
