[Developers] flush-ing stdout in cctk_vinfo

[Bela Szilagyi]

Erik,

I am using the 

-bno -reo 

options but these do not work.  I.e., in spite of my command line

cactus_harm -reo -bno myparfile.par >& mylogfile.out

I am loosing output lines in various CCTK_Proc[...].out files.

Adding 

 fflush(stdout) ;

into my own code, after CCTK_VInfo(...), has solved the problem.

So my suggestion is to add the fflush() into CCTK_VInfo(...), perhaps 
conditional to an extra parameter.
