[PATCH] New changes to ext_skel for C++

Taking a few comments into consideration, here's a new patch for adding C++ code-generating abilities to ext_skel. The new patch doesn't use a separate skeleton.cpp file. Instead, it adds some lines like /* __begin_extern_c__ */ /* __end_extern_c__ */ to skeleton.c and lets ext_skel either replace them with the proper C++ stuff or get rid of it altogether. I didn't want to make the extname.c output any more complicated with #ifdef __cplusplus preprocessor nonsense, 'cause having extension first-timers asking why there's C++ stuff in their C file would suck. Another slight change to skeleton.c just gets rid of the string named "string" and replaces it with "str". This is just to get rid of any conflict that might come up if someone #includes the C++ string library in their extension, so they don't need to worry about C-string named "string" being confused with the C++ data type "string". Comments? J
