XAML-backed controls - hook up XAML markup to the UIViewController via outlets

CHANGES
=======
1. XamlUtilities contains XAML helper methods: ReturnXamlType and GenerateUIKitControlfromXamlType
2. Added initWithFrame:xamlControl: to UISlider and UITextField
3. Modified sample app, XAMLTest, to exercise UIKit controls updating label text as other controls are manipulated
4. Checked in a binary drop of Xib2Xaml.EXE and XamlTools.DLL

TESTS
=====
Unit tests PASSED
XAMLTest (desktop/ARM) and WOCCatalog verified (desktop)
