Add support for key modifiers (e.g. Control + Shift + A)

[nomis51]

I see in your Example folder here a method called CombineKeys that is not currently available.

Do you plan to add key modifiers to the keyboard methods already available, such as KeyPress :
KeyPress(Key.A, Key.Control)

That's a very usefull feature for any kind of projects that manipulate the keyboard "like a human". Those things are currently doable in AutoHotkey and in other .NET Windows-only libs, so I hope it gets implemented here aswell.

Workaround I have to do now is to Key down a modifier, such as Control, then Key press my target key, then Key up the modifier. That's fine, just not clean in my opinion.

var robot = new Robot();

robot.KeyDown(Key.Control);
robot.KeyDown(Key.Shift);
robot.KeyPress(Key.A);
robot.KeyUp(Key.Shift);
robot.KeyUp(Key.Control);

// instead of just overlaoding the method with
robot.KeyPress(Key.A, new []{ Key.Control, Key.Shift })

If you take a look on CombineKey, it does the same that you proposed here. In fact it is not working as expected because I need to manage the modifiers flag when I do a keydown / keyup.

I have not tested yet but the solution looks like this guy did in this fork:

I'll test and if works I'll make a MR
