++ Added char map to slugify words with accents and special chars.

[ericzon]

I'm using your great set of components and I needed to slugify words with accents.
Before "ÁÉÍÓÚáéíóú" turned into "", now it turns into: "aeiouaeiou". Hope this helps.

@ericzon great idea! I hadn't thought about that possibility. I think it makes more sense to have a function which has the sole responsibility of replacing accented characters, and just use that function prior to slugifying where needed. That way, you can reuse the accent stripping function in other contexts and keep the slugify function lighter.
