Redirect path on Confirmation is broken

If your Drupal site is not at the root of you webserver, the "Redirect path on Confirmation: " will not work.

Suppose your have the following:
* drupal site url: http://localhost/my_drupal/
* Redirect on confirmation: node/3

After clicking an email confirmation link, and taken to the user edit page, the url will look like:
* http://localhost/my_drupal/user/31/edit?destination=/my_drupal/node/3

Note that the destination param should be "node/3" not "/my_drupal/node/3"

r1.123 started using drupal's url() function to build the destination parameter. I believe this is wrong.

The attached patch removes the use of url(), lets drupal_goto() handle the urlencode()ing of destination, and passes the fragment as an argument to drupal_goto().
