* Fix some comments in custom/conf/app.ini.sample

Some comments in app.ini.sample were very vague, didn't contain much information.
Some of them have been fixed, but mistakes that need to be fixed by an expert still remain, see #3928

* add config option to enable or disable log executed SQL

* rename ShowSQL to LogSQL

* 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.
