Output goes to weird places when logfiles are specified because of Write(6,*)

In testing multirun mode, I am noticing that although most output from Rayleigh is handled through

stdout%print()

a fair amount is handled through

Write(6, *)

Normally, this will all go to the same place (terminal screen) so if someone just redirects the screen output, say,

mpiexec 2048 ./rayleigh.opt > logfile

it will be fine. However, if a logfile is specified (which we must do in multirun mode),

stdout % print

will go to the logfile, and

write(6, *)

will go to the "screen" which is likely the parent directory.

Unless I am missing something, it seems like Write(6, *) should never be used in the code, only stdout%print ?

Doing a grep looks like these write(6,*) statements appear 49 times. Happy to make a pull request fixing this (if I haven't missed anything) but it will change quite a few files. Can also wait until version 1.0
