Routine to dump the current source term used in invert_rhs.
This might be relatively expensive so care should be taken in calling this. It makes use of the existing code for saving restart files and as such produces either one file per processor or a single file depending on if the build uses parallel i/o or not. These files are automatically overwritten so calling it repeatedly within a single run might not be useful.
