Double unicodes

One other change coming with 2.5 is the support for more then one unicode per glyph. It is stored in the file like this:

unicode = "005A,007A";

(I first tried to skip the quotes, too. But neither Apples code nor the glyphslib parser liked it 😉

Internally, this is handled by two properties. One called unicode and it returns the first unicode if any. Then there is a unicodes property as an NSOrderedSet.

I though about changing the key in the file to unicodes but that doesn’t make a lot of sense.

One reason why I didn’t use a list (like unicode = (005A, 007A);, is at the double unicodes are now commonly used and having either the parenthesis in all cases or different cases (a string for single and a array for multi) would be more complicated.

It can even read the version without quotes like unicode = 005A,007A; because it turns out that Glyphs 2.4.4 writes it that way
