Profile.url doesn't redirect properly 'without http://'

If a user inputs a personal url without http:// the template is rendered with {baseurl} + users profile.url. 

Example: if you have www.christopherjaynes.com or christopherjaynes.com on click you are directed to

http://www.julython.org/topherjaynes/www.christopherjaynes.com

and 

http://www.julython.org/topherjaynes/christopherjaynes.com

Live examples:
http://www.julython.org/topherjaynes/
http://www.julython.org/simon_weber/

Should be handled when data is added to DB, but since it's close to the end of the month added to template so you don't have to clean current data.
