Commented Issue: ShouldBeEquivalentTo crashes on signature hiding properties [12481]

Take this example. Foo is overriden with new. This crashes TypeExtensions.FindProperty because it will see object Foo and string Foo

```c#
[TestMethod]
public void FluentAssertionsTest()
{
var a1 = new B<string> { Foo = "test" };
var a2 = new E<string> { Foo = "test" };

a1.ShouldBeEquivalentTo(a2);
//a1.ShouldBeEquivalentTo(a2, ex => ex.Using(new MustMatchByNameAndTypeRule()));
}

public class A
{
public object Foo { get; set; }
}

public class B<T> : A
{
public new T Foo
{
get
{
return (T)base.Foo;
}

set
{
base.Foo = value;
}
}
}

public class D
{
public object Foo { get; set; }
}

public class E<T> : D
{
public new T Foo
{
get
{
return (T)base.Foo;
}

set
{
base.Foo = value;
}
}
}
```

My suggestion is to add 2 new matchers:
```c#
public class MustMatchByNameAndTypeRule : IMatchingRule
{
public PropertyInfo Match(PropertyInfo subjectProperty, object expectation, string propertyPath)
{
PropertyInfo compareeProperty = expectation.GetType()
.GetProperties(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance)
.SingleOrDefault(pi => pi.Name == subjectProperty.Name && pi.PropertyType == subjectProperty.PropertyType);

if (compareeProperty == null)
{
string path = (propertyPath.Length > 0) ? propertyPath + "." : "property ";

Execute.Verification.FailWith(
"Subject has " + path + subjectProperty.Name + " that the other object does not have.");
}

return compareeProperty;
}

public override string ToString()
{
return "Match property by name and type (or throw)";
}
}

public class TryMatchByNameAndTypeRule : IMatchingRule
{
public PropertyInfo Match(PropertyInfo subjectProperty, object expectation, string propertyPath)
{
PropertyInfo compareeProperty = expectation.GetType()
.GetProperties(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance)
.SingleOrDefault(pi => pi.Name == subjectProperty.Name && pi.PropertyType == subjectProperty.PropertyType);

return compareeProperty;
}

public override string ToString()
{
return "Try to match property by name and type";
}
}
```
Comments: Thanks. I'll incorporate your changes in 2.1.
