Add a flag #RunAsAdmin (?) to the to RunProgram() function

[Marc56us]

Please add (if possible) a new flag for RunProgram() to run program as administrator.

I know there are examples that work well (Windows)

but a native function would be interesting

Linux can call 'sudo'.
For Mac, I don'k know.

Thanks
