Bump $VERSION to 1.011
README: changelog for release 1.011
Move config rules for ssh.github.com above *.github.com

ssh_config parsing rules keep only the first value set to an option. Our
rule order was broken for hosts gist.github.com and ssh.github.com (and
their *.gist.github.com and *.ssh.github.com aliases).
Really fixes #12.
Fix update of known_hosts_github file

The size check had to be updated for the update to be triggered.

Also, the known_host entry for ssh.github.com is now specific to port
443: ssh checks this entry first (before a more generic
"ssh.github.com" entry), so this *may* speed-up connection.
Add *.443.github.com as aliases to *.ssh.github.com
