AL: 1. Ported COOLFluiD to use long long int.

    2. Updated installation script to include --int64 flag for installing PETSC using long long int. 
    3. Updated prepare.pl script to include with_longint flag to compile with long ints. 
    4. Compilation is now successfull but the code does not run, at least with OPENMPI, (partitioning problems) if long int are enabled.
