Addressed issue related to configuring methods of base interfaces (AutoMoq)

This fixes issue #306.

The `AutoConfiguredMoqCustomization` will now be able to configure the following methods:

**Example 1**
```csharp
public interface IInterface
{
    string SomeMethod();
}

public interface IDerivedInterface : IInterface { }
```
**Example 2**
```csharp
public interface IInterfaceWithShadowedMethod
{
    //shadowed method
    string Method(int i);
}

public interface IInterfaceWithNewMethod : IInterfaceWithShadowedMethod
{
    //new method
    new string Method(int i);
}
```
**Example 3**
```csharp
public interface BaseA
{
    string Method();
}

public interface BaseB
{
    string Method();
}

public interface Derived : BaseA, BaseB { }
```



Notes:
* AutoMoq now depends on Moq 4.0.10827, as discussed here: #306 
* While writing this fix, I came across another bug in Moq, reported here: moq/moq4#131
