possible fix for proximity filter based on user location

Here are the changes I made to allow proximity filter based on user location.
I have never submitted a drupal module change, so let me know if there is a better way to do this.

Depends on views, location, and user location.

Thanks,
Ben

PS. I use this to restrict display of events(nodes) to those close to the user.
