Log:
 GRHydro: remove comparison of logical to .true.
 
 I appreciate the effort to make the code compile with gcc by no longer
 using integers in place of logicals. I really do. However it seems that
 F0RTRAN in its infinite wisdom requires you to write
 
 ... .and. mustbisect .eqv. .true.
 
 (note the all important 'v') when testing logicals. I have instead opted
 to remove the whole .eqv. term in favor of
 
 ... .and. mustbisect
