Changed registration into a complete form.

Instead of hoping users will go back in after account confirmation and fill out their details, the entire profile is part of the registration process.
Used simple_form to clean up form.

Added proper required fields and changed Ruby syntax in some areas.
Removed account status.

Account path routes to profile edit path. Removed profile completion logic. Removed new password required option.
