Patch for "Out-of-line docs for class template specialisations failing"

When documenting a class template specialisation out of line, the template arguments are interpreted as the second argument, i.e. as the header-file argument. Example of the problem:

>// a.cxx
>
>template<typename T> struct A { };
>
>/// \brief Correctly documented specialisation
>template<> struct A<bool> { };
>
>template<> struct A<int> { };
>
>/** \struct A
> *  \brief Some class template
> *  \tparam T Name of the type
> */
>
>/** \struct A<int>
> *  \brief Non-working specialisation
> */

Use these commands to generate a default Doxyfile and to run it:

>$ doxygen -g
>$ doxygen
>[...]
>[a.cxx]:15: warning: the name `int' supplied as the argument of the [\class] command is not an input file
>[...]
>[a.cxx]:8: warning: Compound A< int > is not documented.
>[...]

The attached patch fixes the problem for me, but it has two problems:
* It breaks old (potentially undesired) functionality: \class A<a.h> (without space) was allowed before but fails to work now
* The QRegExp cleanup is probably not ideal. There must be a better function to call to get the canonical class name.
