Links_weblink url field please?

Issue Summary

Hi,
Thanks for already a great module. The title-uniqueness is great!
I would very much like also not to have double url's in my database.
I use the ad.module and links_weblink.module for url's.
Could you please may be add the url-fields to the chosen fields for these contenttypes?

Thanks a lot for considering this! Or are you building an api, so I can easily add these fields or other fields from other contenttypes to this module?

greetings,
Martijn
