the fixed version

I attached the modified version of your demangler. It has many fixes including
the current bug.

P.S. "get_type_encoding" - it's the reversed code from dbghelp.dll. You can
make it more beautiful if you need :))

P.P.S. I'm going to remove "handle_data" from sources and use the common
"handle_method"
