The "Modules" key (WindowsRegistryFinder in 3.3+ and previously
PyWin_FindRegisteredModule) adds individual modules by subkey name,
with the filepath in the default value (the filename can differ, but
it can't use an arbitrary extension). The "PythonPath" and "Modules"
keys both date back to Mark Hammond's Windows port in the mid 1990s.
