Initial commit for new dw_signal_connect_data() function...
Same as dw_signal_connect() but it has an additional callback
parameter that gets called when the callback is being removed.
This allows me to free memory allocated for the data parameter
and prevent memory leaks in godwindows... Tested GTK and Mac.
