Bug #6660 mysqldump creates bad pathnames on Windows

This is a modifiction of my previous patch after receiving feedback. This is a better way to fix the problem.  With this patch, data directory and index directory will use only forward slashes (/) when on Windows.

mysqldump.c:
  Removed fixPaths routine.  Was improper fix for bug #6660
sql_show.cc:
  Changed append_directory to convert backslashes to foward slashes when on Windows.
