[FIX] website : fix visitor cookie expiration

Before this commit, the visitor cookie was expiring by default on
browser session close on firefox. On Chrome, the cookie was always
valid after browser session closing.

On Firefox, the expiration date must be set to make the cookie still valid
after closing the browser.

The same thing happened with livechat_session cookies set
in context of livechat request.

The cookie expiration date (100 years to 'never' expire) have been added.
