RealName uses a fully themed html link for the homepage url when using content profile

As far as I can tell, when RealName is set to use Content Profile to get its data, the value it gets for the website field is always a fully themed html link. Let me know if I'm somehow mistaken.

It looks like this can probably be fixed by changing the content_profile_load_profile() function in realname_content_profile.inc so that when it gets a value for a link field, it always just gets the url.

From my limited testing, using a 'plain' formatter wouldn't work, because it grabs the title if there is no url, and that would mess RealName up. Grabbing the 'url' element from the $content array seems to be the best bet.

Also, at some point, something should probably make sure it starts with http:// (or https://), adding it if necessary. Maybe later in the pipeline?
