Make swap values case-INsensitive

[tedyoung]

I regularly run into the situation where I've used a swap (hx-swap and hx-swap-oob) value of innerHtml instead of innerHTML (for example), which causes things not to work as expected.

Why are innerHTML and outerHTML case-sensitive?

If there's a good reason, then these values should be clearly marked with a warning that they're case-sensitive, otherwise (my preference) they should be case-insensitive to avoid such problems in the first place.
