Always normalize urls

[ewinslow]

forward() has this nice property where if I forward to 'pg/some/page' it knows to prepend my site root before forwarding. This should happen everywhere.

• adding menu items
• output/url
• output/confirmlink
• others?

Create an elgg_normalize_url() function.

As of [svn:7223] this isn't working correctly for the profile plugin. The topbar icon doesn't have the correctly URL.
