Update invasion gates to show the status of the other side

We should not have to rely on 3rd party tools in order to determine the invasion status of a system. You spent time developing gates to have icons to show vartious bits of information, surely it woulkd be logical to include there the various states an invasion system can be in. With more and more systems showing as invasion system it is getting more and more difficult to move around freely without knowing what is on the other side of a gate.
