Files has some broken-ness

Update comments.php

The line "$comment['user_website'] = $this->current_user->website;" was removed in this commit: https://github.com/pyrocms/pyrocms/commit/73788f4a7d66519756a03f30e09f1468f553be37 

$comment['website'] = $this->current_user->website; 

The model insert user_website, not website. I see using of 'website' only in the display view of 2.3 on line 11 https://github.com/pyrocms/pyrocms/blob/2.3/develop/system/cms/modules/comments/views/display.php#L11.
This needs to return something - so let's return something impossible

We also need to test if salt is available - if the column doesn't exist - this obviously isn't an old login hash
