Custom shell config

[Postremus]

Feature idea

Right now, the shell to be used is defined in PackageManagerRunner#runner. For windows, cmd.exe /c is used by default.
I have however on my system problems with executing npm.cmd from within the normal cmd.exe.
Therefore, could you please provide a config option to customize the shell used? This would allow me to run with cygwin, or powershell.

Additional information

I think its more invasive than just that command it also looks like its here in PackageManagerType

public String getOSBinary() {
        return isWindows() ? binary + ".cmd" : binary;
    }
