Implement a footer-navigation-item (#68)
The footer navigation item will contain "powered by", "hosted on", and "help" links.
Used "footnav" and alter the existent template.
Aftern implementation, suggest this change to be included within the main trac-project with the following logic:
if "small-logo" defined (in trac-ini) use it before the footnav, otherwise do not use i and use the footnav alone.
