[FIX] website_event: better sold out computation

Purpose of this commit is to remove some complex check embedded in templates
and replace them by a computed unstored field. It eases definition and
understanding.

Its computation has been cleaned, so that sold out appears only when tickets
are really sold out, not if their end sales date is reached. Sold out label
is displayed in both event list and event specific page views in frontend.

Small spacing issues in frontend registration form are also fixed.
