R# SSR patterns to assist in migrating from obsolete ShouldBeOfType<T>

The .dotSettings file can be added as a settings layer in ReSharper 8 and offers two Quick Fixes:
1. Replace expression.ShouldBeOfType<T> with expression.ShouldBeOfExactType<T>
2. Replace expression.ShouldBeOfType<T> with expression.ShouldBeAssignableTo<T>

The migrations can be done one by one using Alt-Enter or a whole project at a time by selecting "Find Now" from the Pattern Catalog.
