Alternate card styles (unicode characters)

[kbjr]

I can add (and am adding) support for various types of "alternate" card styles, but full support is waiting on an addition to unicode to add proper support for these characters (likely as variants of the existing characters). If this ever happens, update the unicode characters for the appropriate cards.
