like /tools/mspsim. This is a very simple modification that affects a very large number of files in Contiki: Cooja, /platform/cooja, Collect-view, Coffe-manager, and Cooja simulation files (.csc). I've gone through Contiki to update all references I could find. Nevertheless, this commit will likely break external dependencies, like saved Cooja simulation files.
