[PD-dev] removing pd/bin/msvr*.dll from Pd/win

I bet most externs use one or another thing from msvcr*dll.  String
functions, malloc, etc...

Here's an idea, what if I stuck  msvcr*dll in a separate directory and
called SetDllDirectory another time in s_loader.c to allow externs to find it
if they need it?
