Type safe connect doesn't handle default parameters

When using type-safe connect() methods (taking functors), the default values for parameters are not taken into account when looking at signal-slot compatibility, e.g.

void someSlot(int a, int b = 0);
void someSignal(int s);

There should not be a problem connecting this signal to slot, and it's possible using the old SIGNAL() and SLOT() macros. When using the type-safe versions:

The slot requires more arguments than the signal provides.
