Better URLs for users

People were complaining that the LibraryThing URLs were too complex and it was hard to find the URL for a direct link to your collection. From now on you can use URLs like:

• Your profile — http://www.librarything.com/profile/timspalding
• Your catalog — http://www.librarything.com/catalog/timspalding

The catalog one will "redirect" to a more complex URL, the server rules being extremely difficult and hazardous to play with while dozens of people are on. Your URL is also listed on your profile page.
