[Pharo-project] RPackage and Monticello are dependent on each other

Hi, we have small dependency problem. The RPackage is currently dependent on Monticello and Monticello is dependent on RPackage. This makes them unable to load them to Pharo Kernel. I suppose this will fix the worst: MCPackage organization renameCategory: '*RPackage-Core' toBe: '*RPackage-SystemIntegration'. I will open an issue. Cheers, -- Pavel
