Merge branch 'widgets' into card

Conflicts:
	card.py
at least the cards *display* now, if not correctly, and although they do nothing
There's a hand with cards in it and you can rearrange them as you like. Well, I haven't tested the case where there are more than two cards because that is all that will fit in the GUI as it stands. I'll widen it, or else let the text get real tiny.

I will need something like in Magic the Gathering Online where double clicking a card shows you just that card in "full screen".

moved this shit into gui.py

Edges (representing portals) now have little arrowheads on them to indicate which direction they go.
