Chosen letter support (Unsets)

[Northmoc]

A decent draft, I think

In case you’re wondering, we’ve chosen to allow Y to be both a consonant and a vowel, depending on what the card cares about. Y? Because we’re nice, and because Y has a great legal team.

Apropos Letter in Card Name, we should normalize them for names like Bartolomé so é counts as e

see:

forge/forge-core/src/main/java/forge/util/TextUtil.java

Lines 49 to 54 in 1bee1a4

	public static String normalizeText(String text) {
	if (text == null)
	return IPaperCard.NO_ARTIST_NAME;
	return Normalizer.normalize(text, Normalizer.Form.NFD);
	}
