qt_reps_from_headers generate wrong REP

Two issues:

1. enum defined in the header won't be recognized.

       enum MyEnum {
           Foo = 0,
           Bar = 1,
       };
       Q_ENUM(MyEnum) 

2. signal generates a return type, which cannot be recognized by qt_add_repc_sources
   for example 
   void sayHello(QString name);
   generate 
   SIGNAL(void sayHello(QString name)); // WRONG
   SIGNAL(sayHello(QString name)); // RIGHT

please see the attached example
