Files: source in lib, gibbs, minmd, sander directories

Severity: slight

Problem:  On Cray machines running Unicos, the automatically supplied
     environment variable CRAY makes it difficult to generate source
     for other machines using mksrc. This is because Cray-dependent
     code automatically gets included by cpp since the keyword CRAY is
     used in #ifdef sections within the code.

     Generating source for another machine on a Cray is a relatively
     unlikely scenario, but it is prudent to use another keyword to
     allow more control over the use of cpp.

Fix: substitute CRAYFISH for CRAY in all ifdef lines in the 
     following files:

       lib:   ene.f force.f nonbon.f openda.f resnba.f
       gibbs:   machinedep.f (beware of the ICRAY1 variable)
       minmd:   efield.f indip.f minmd4.f polder.f
       sander:   nmr4.f

     and substitute also for the MACHINE definition in these files:

       Machine:   Machine.Unicos Machine.ctss
       and src/MACHINE if your machine is a Cray.
