Remove template arguments from the class name in the member function

[vitaut]

The proposed PR removes template arguments from the class name in the member function. Otherwise links to nested classes (in parameter or return types) defined in the same template are not generated correctly, because the latter don't include template arguments.

For example, void C<T>::f(D) is converted to void C::f(D) in

/** A class */
template <typename T>
class C {
 public:
  /** An inner class. */
  class D {};

  /** A method. */
  void f(D);
};

Fixes #179.

@michaeljones, if you merged #189 first, I could also add a unit test for this.

Thanks for the prompting, I've just merged and pushed that other branch.

I haven't had a chance to properly look at your code. I'm sure it is great but I'd agree with you that it is the sort of thing that goes well with a test or two to double check.

Thanks for picking up on the issue and fixing it as always. Sounds like a good choice to me.

Thanks for merging the unit testing branch. I've moved the code that removes template arguments to a separate function and added a unit test for it.

It looks great. Thanks for catching it and fixing it. I've just adjusted the indentation in the test code and added a comment or two to help me out.

Much appreciated as always. Merge if you're happy with the changes.

Thanks for the review and code improvements. Sorry about about the mess with indents, I got used to 2-char indents and sometimes forget to adapt to the surrounding code =).

No trouble at all. I sometimes flirt with 2-space indentation and understand how annoying it is to keep per-project configurations. An understandable situation!
