Feature request: Support for entityID

[kontu]

Some day if you're bored would you mind adding EntityID to fixship? This lets admins pair it with things like listgridsowner -id to fixshipmod stuff from out of game if need be (such as if a player isn't around and the grid looks to be causing issues in other tools)
