Add a ShowContactTask to show a specific contact's details
If I have an app that shows a filtered subset of a user's contacts, I should have a way to click on that user and show the user's details in the native experience.
I am familiar with the suggestion to take the contact's details and re-create them in your own UI... which would be great if the API exposed all of the user's details (like the Anniversary) which it does not. Also, having a ShowContactTask would allow me to give my user a quick shortcut to post a message on Twitter or Facebook without having to implement those SDKs (especially since the APIs do not currently give you access to social networking contacts to be able to pull their social network handles).

I would love to have this so I wouldn't have to create all the UI to store and edit contacts within each app. But to complete this there would also need to be a ContactChooser that returns a key that could be passed into ShowContactTask. Please add support for this.
