v1.0.7 - Temporary user sign-in fix

Fixed

• Temporary users can now access sign-in page - Previously, temporary users clicking "Sign in" were redirected away because user_signed_in? returned true. Now checks permanent_user_signed_in? instead, allowing temporary users to sign in with a real account.

Added

• Referrer-based redirect after sign-in - When users voluntarily click "Sign in" (not forced by require_authentication), their referring page is stored so they're redirected back after signing in. Security: only stores referrer from same origin.
• permanent_user_signed_in? helper method - Returns true only if user is signed in AND permanent (or doesn't respond to permanent?)
