Bug 24060 – Improve "Cannot create instance of abstract class" error

When you try to create an abstract class, like this: ``` import std; abstract class A { abstract void foo(); } class B : A { } void main() { B b = new B(); } ``` you get this error: ``` onlineapp.d(15): Error: cannot create instance of abstract class `B` onlineapp.d(15): function `void foo()` is not implemented ``` Note that it points to where the class is being created (line 15), not to the class `B` itself where the erorr happens. I think a reference to where class `B` is defined should be added. It will be convenient for IDEs to ctrl + click to follow where the class `B` is defined. Also, "function `void foo()` is not implemented" should point to line 5, the place where the abstract function is defined.
