Tracker - world logs

I've updated the world info a bit - and you can now add logs.  I think if the world is part of that I need to figure out if I want to include the world info on the ship log as well.  I may have to add some more info about if this is a general note or a ship specific one or something.

I've also updated the refuel process to use the port's fuel.  And then realized I've not added a way for you to add a new port or delete a port.

Maybe tomorrow I'll have time to figure out the image thing. Or not - we're off to see the Russian Ballet.  A little bit of real world culture.
