Formal Review of std.process

[Lars T. Kyllingstad]

I wonder if we should change the name of Config.gui to 
Config.noConsole.  It corresponds to the CREATE_NO_WINDOW flag in 
the Windows API, for which the documentation says:

"The process is a console application that is being run without a 
console window. Therefore, the console handle for the application 
is not set. This flag is ignored if the application is not a 
console application [...]"

I know some people don't like negative flags, but in this case it 
seems more precise.  It doesn't create a GUI, it prevents the 
creation of a console.
