Drupal 7 port

Hi,

Here is fully working Drupal 7 port of this module. I ran it thru the coder module to get it code compliant with the new changes on Drupal 7. Also the administration path is updated as well. Please test it and post your comments.

Note: I was surprise to see that only 7 sites report using this module, that is really odd.

Thank you,
Emil
