[issue3561] Windows installer should add Python and Scripts directories to the PATH environment variable

For 3, installing the PEP 397 launcher will be the long term "on-by-default" solution.

For 2, adding the Scripts subdirectory seems reasonable.

FWIW, Window used to have *very* severe restrictions on the maximum length of PATH, as well as gratuitously long names for standard executable file locations. This made conscientious developers understandably reluctant to mess with PATH, because adding to the start could break other elements of the user's system, while adding to the end wasn't reliable.

This is much less of an issue these days, as Windows is a lot more tolerant of ridiculously long PATH definitions.
