Automatic Redirect to Node's Alias

If more than one alias is specified for a node, redirect to the alias that is listed in the node itself if any other alias is used.

This would prevent duplicate content when using multiple aliases to a page, such as:

http://school.edu/node/10
http://school.edu/admissions/apply
http://school.edu/apply

If any of these URL's are used, it would redirect to whichever alias was shown on the node's edit page.

This functionality can be done by using the Path_Redirect module and changing all the other alias to redirects, but it would be much simpler to have this built into Global_Redirect and not need the Path_Redirect module at all.
