Verbose console output by TStringBuilder.ToString

We are using TMS Web Core 2.7.2.2 and wonder why there is a WriteLn statement without a surrounding {$IFDEF DEBUGXYZ} in unit sysutils.pas, TStringBuilder.ToString. In our case, this generates a huge amount of console output and makes it harder to find our own console output.

That should indeed not be there. It was for debuggin purposes. We removed it.
