Fix for detecting C/C++ in function list (fixes notepad-plus-plus#457, …

…closes notepad-plus-plus#609)

 * Detect C functions: `void ** VoidStarStar ( )`
 * Detect C++ functions: `void ** VoidStarStar ( )`
 * Detect C++ functions: `int& RefReturnValue ()`
 * Detect C++ methods: `void ** Class::VoidStarStar ( )`
 * Detect C++ methods: `int& Class::RefReturnValue ()`
