 GRHydro: add SAVE attribute to module variables
 
 I forgot the SAVE options since my initial google search seemed to
 indicate that they are redundant. It turns out that is only true for
 Fortran 2008 and an earlier Fortran compiler would in theory be free do
 have variables use their values once the last procedure using the module
 goes out of scope. This seems to be not done by any compiler though.
