PPCTask Memory not freed after ending of WarpOS program  #6

ReWarp emulates PPCTask structures by keeping a shadowlist of PPCTask structures for each WarpOS OS4 task. When a FindTaskPPC or CreateTaskPPC is performed, the functions return the PPCTask instead of the actual OS4 task. However, the memory needed for these PPCTasks is not freed upon ending the WarpOS OS4 task (220 bytes per task).
