Search TextBlock horizontal alignment centered
StackPanel for SearchIcon and TextBlock "Search" was added. Methods "SearchTextBoxGrid_MouseEnter" and "SearchTextBoxGrid_MouseLeave" was changed due to needs of moving icon and text block. Now when mouse moves on SearchTextBoxGrid StackPanel moves at the left side.
Search Panel was fixed: on mouse click it aligns to the left edge, also alignment now depends on Converters class. There is c# code only in Conventers class and there is only one method in SearchView - SearchTextBox_MouseDown.
Ben, as you wrote "to use IsKeyboardFocusWithin or something similar", I have tried to use Focus of TextBox as Binding element, but there is one problem: if we have some text in textbox and than lose focus, our icon appears at the center. That's why using focus for binding is wrong solution.
What I propose is to create new property in ViewModel. I called it CanAlingmentToLeft, that would depend not only on Focus, but also on value of textbox. Hope that you will accept this solution.

Renamed from Tooltip in ToolTip, Input/Output are now only in NodeSearchElement. DynamoPopup now includes TooltipWindow, so it's 1 class. DependencyProperty objects removed, now tooltip uses Datacontext.
