Traveller Tracker - cosmetic updates, some under the hood updates

I've added the credits available to the editor, did a bit of bolding for the labels, and aligned things a bit more.

I've also expanded out the ship listing to give the ship class info, and may end up adding the current world and date.

I need to design the actual ship tracking view, which will give a different set of options such as setting the jump (find the list of worlds within jump range - I can either redo the math I had earlier or use the TravellerMap API. May be both - 1 to show an jump map, the other to list the systems); cargo handling (buy, sell) and whatnot.
