Load Balancer PUNCH!

Configures port 81/82 and 44301/44302 to punch through the load balancer directly to the individual instances.

Also, adds Instance ID to footer. Non-admins can see this, but it's nothing users can do anything with.

(Original was going to use 444 and 445 for SSL, but 445 is SMB and the load balancer really doesn't like it if you use it).

This is going to be part of #938 so it's a PR to the rest of those changes. Separated out the Code Reviews because they are somewhat separate.
