Title: Code effeciency project:  Canister icon updates

Before: If a canister is hooked up to a connector port it's icons were being deleted and recreated every tick.

After: We store an update_flag that is a bitfield of the current icon and overlay states, and created a proc to check if it should change. If not, we don't mess with icons. Real simple.
