Bug：Move interface method causes compilation errors.

[DongChunHao]

move interfaceMethod() to MyClass to classes causes compilation errors

interface MyInterface {
// move interfaceMethod() to MyClass;
void interfaceMethod();
}

class MyClass implements MyInterface {

@Override
public void interfaceMethod() {
	
}

}

@DongChunHao This move is a textual move which means it is a cut/paste operation without checking hierarchy, implementers, etc... I have created a patch that will restrict moving an interface method to anything other than another interface (something a user may reasonably want to do). IMO, this is a reasonable check as moving such a method declaration anywhere else makes no sense. As mentioned, there is no additional checking done (e.g. verifying that there aren't any implementers out there that will be broken when the method is moved).
