Strange slug translation of "ä"

I kind of like the not so official solution by @distantnative. The only thing is that it does not look like a native config.

Maybe somthing like this could make it more standard?

c::set('ascii', array(
    '/Ä/' => 'A',
    '/æ|ǽ|ä/' => 'a',
    '/œ|ö/' => 'o',
    '/Ö/' => 'O',
    '/ö/' => 'o',
));

And it will only change matched characters. The rest could still use the core character translation.

Maybe change ascii to something more telling.
