Fix for issue #68

Based on the demo site in FF, Chrome and Safari none of the list filters seem to work.

Steps to reproduce:
1) Go to http://djangosuit.com/admin/examples/country/
2) Select Africa in the Continent drop down
3) Press Search

Expected:
List to be filtered by Continent=Africa

Actual:
List is not filtered

I believe the issued is related to the way the code is populating the "name" and the "value" for each option

The following patch should fix it
