* Add an option to allow redirect of http port 80 to https. This is an "opt in" option (default is to not redirect). It will only redirect if protocol is https and the new REDIRECT_PORT_80 option is set to true. The Port to redirect in previous commit was hardcoded to 80, now it can be specified in the app.ini, defaulting to 80. The boolean option to turn redirection on has been changed to REDIRECT_OTHER_PORT to be logically consistent with the new port option. Signed-off-by: Mike Fellows <mike.fellows@shaw.ca>
