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.
se.sics.cooja.GUI -> se.sics.cooja.Cooja
this commit does not contain any functional changes, but may require external scripts to be updated
such as Makefiles.
