User integration

1. No additional login module required. One of our earlier aim is to remove any needs for separate login modules. Joomla built-in login module should be good enough. I understand a lot of template club already have a custom coded login module and it would be a waste not to be able to use those.

2. No required profile field. All profile field are optional and fully customizable. We do not want to force you to have any additional field if you don't want to. If you do specify it however, the registration page will present these fields as you would expect.

3. Doesn't need any database sync. None whatsoever. We want all user to integrate seamlessly with the rest of your site.
