Removed duplicate entries (1.6.1-1.6.3) in changelog.

Previously, the get_fqdn() function in known_hosts.py only worked
with urls that started with git@, and ignored any urls that started
with a normal schema type (ie. http:// or ssh://). This patch corrects
that by using urlparse to parse the hostname portion out of urls that
have a proper schema.
