Split up `viewgame`

viewgame is 130KB large.

We should split it up into components, like we did with the home page.

How do you want to split it up? E.g. is the code for pulling game info from the database all going to be in one component, regardless of which section that info actually appears in?

That makes sense to me, yes.
