Allow [DirectoryExists], [FileExists], [PathExists] to be applied to global parameters

[rossipedia]

I'd like to expose a global parameter that is essentially a data directory.

I'm trying to do something like:

[Global("d")]
[DirectoryExists]
public void DataDir(string dir)
{
    this.dataDir = dir;
}

But, of course I can't because the DirectoryExistsAttribute is marked with [AttributeUsage(AttributeTargets.Property | AttributeTargets.Parameter)]

It would be very helpful to allow these validation attributes on global parameters

I agree. Please send me a pull request with the changes and please make
sure there are unit tests that cover this new feature.

Thanks,
Adrian

For sure. I've forked the repo and set up a branch, I'll try to dig in sometime over the next couple of days.
