Some new cmdlets we talked about on codeplex discussion 

Hi, sorry it took a bit longer but I was more busy that usual. I've added 3 new cmdlets that we use in our project:

Invoke-UIAWindowPattern - nothing to say about that really
Set-UIAControlForeground - this is kind of alternative to Set-UIAFocus, I'm calling SetForegroundWindow on control if it has valid handle. I found this more stable than Set-UIAFocus method, mainly on Windows dialogs like UAC or login windows.
Set-UIADateTimePickerDate - this might not work everywhere since it requires write permission to process you're trying to automate (some AV products block these attempts) but in general it works fine

I haven't tried to incorporate cmdlets directly because you already wrote that you need to make some changes to them so files are just in root of repository. I hope these will make your project more awesome than it already is :)
