Lots of changes.
Card rendering is in how it'll be for now. Shrunk down the design quite
a bit.
Spell casting is in for now, but only in the sense of taking something
from your hand, choosing a single target and then placing the spell on
the stack. Resolving the spell is on the todo list.
Updated the font to look a little nicer and include some non-keyboard
symbols for range and cost.
Some python error checking added for calling functions with the wrong
types.
Other stuff, I'm sure.
