This PR implements #2347

* remove old git-version from git-scm url in app.ini

The url includes the version of git, which is not required to view the
page. If you open the page without the version you get the current
version and it's possible to switch the used version.

* Turn swagger.v1.json into template

* Rename ENABLE_SWAGGER_ENDPOINT option to ENABLE_SWAGGER

This makes it easier for user who want to theme but
don't have the ability to know how to customize templates
all that is required is a change in a config option

The reason why I chose the DEFAULT_THEME as variable,
as perhaps in the future we will allow users to chose their
theme whon logged in just like we do with languages

* 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.
