right now the ezplos sent are showed by ETA order, I think its a good idea to have the ability to sort them by lokation (system).
This is useful now bkause the ezploration method in the new map always leave me doubtful about if I send to all the planets in that system.

Do this, or either add a button "ezplore system" in the system view, that ezplores all the unezplored planets on it.
