[C++-sig] Default arguments in pyplusplus

[Niall Douglas]

Hmm, pyplusplus doesn't tell BPL about default arguments at all! 
Surely it should output BOOST_PYTHON_MEMBER_FUNCTION_OVERLOADS() for 
each overloaded function?

Needless to say, the TnFOX python bindings won't work without default 
arguments working :(

I did try adding this on my own, but it's complex. I'm afraid the 
class hierarchy in pyplusplus is fairly complex, complex enough that 
without a debugger it's hard to modify. So I'll have to leave it to 
you Roman!

Cheers,
Niall
