Added PTRACERS package

This allows an arbitrary number of passive tracers to be integrated
forward simultaneously with the dynamicaly model.
 + Implemented so far:
    - basic forward algorithm (time-stepping, advection, diffusion, convection)
    - I/O and checkpointing
    - GM/Redi  *but*  using the GM/Redi coefficient of Salt
 + Not implemented so far:
    - KPP
    - OBCS
 + No specific example supplied (yet) but global_ocean.90x40x15 has the
   necessary data.ptracer file. Simply use -enable=ptracers and uncomment
   line in data.pkg. PTRACER01 then reproduces Salt exactly.
 + This package is disabled by default since it increases storage.
