Need a way to access the latest version of the docs without specifying a version

[tst-lsavoie]

Describe the bug

There is no way to access the latest version of our documentation without specifying a version number. For example, we used to be able to go to something like:

http://www.opengee.org/geedocs/answer/fusionTutorial/about.html

to get the latest version of that page. Now we can only access that page if we pick a specific version:

http://www.opengee.org/geedocs/5.3.7/answer/fusionTutorial/about.html

This is a problem when we want to use a long-lived link that always references the latest version of a given document. There may be links out in the wild that are now broken because of this.

To Reproduce

Go to http://www.opengee.org/geedocs/answer/fusionTutorial/about.html. The page will not load.

Expected behavior

Going to the above page will take you to the latest version of that document, regardless of its version number.
