CharacterLoadService Updated

Preliminary CharacterLoadService finished. Some complicated stuff, like skills and special qualities and crud, still needs to be done, but the easy bits are probably all set. Also, I've added an example of how to use the stub service with a File reference (seriously, not. that. hard.) Until you're confident you've got the UI fairly stable, use the stub service to do your work; when you feel it's ready, switch over to the real service.

Also, here's a sketch of what the UI should look like. We should run any designs past Rachel to see how usable she finds them, and incorporate feedback accordingly. The image is an example & rough guide; don't go too nuts over exactness. It also has some "in a perfect world, I want this" stuff in it.
