EmployeeDirectory needs to be ported to WinPhone 8.1

[jgold6]

I think the issue is that a newer version of Microsoft.Phone.Controls.Toolkit is required that removes all of the types that are duplicated in the now included WinPhone assemblies. See:

Once the above is done, any XML that refers to LongListSelector needs to have
toolkit:LongListSelector

changed to

phone:LongListSelector

in order to refer to the new location of LongListSelector

However, the new LongListSelector type does not have certain properties that were used before, like:

1. GroupItemsTemplate
2. GroupItemPanel

So I removed XML elements referring to those properties to test. The app does run with the above changes, but no employees are shown since I had to remove the above properties with their associated bindings.

However, not being that great with XAML and Bindings I did not know off hand how to make it work without those elements.
