Now the SMPI replay tool supports the modified MPE profiling tool.

Now the SMPI replay tool supports the modified MPE profiling tool.
What is new:
1) For most of the collective communications we can know exactly which rank is the root one.
2) Now we can include in the traces the real used MPI datatype (till know we were using the MPI_BYTE). Also we can have multiple datatypes in the traces.
3) The tool supports both time-independent traces from the TAU and the modified MPE tools.
4) Fix Reduce action, as there was no information about computation load.
