Add a few validators #11

ifEmptyList, similar to ifEmptyDict and ifEmptySet but for Lists.
ifContains and ifDoesntContain for checking Strings against a regular expression.

I don't think these are especially good names, but they are useful functions (at least for me.)

Thanks! I merged https://github.com/rtfeldman/elm-validate/pull/9 which added ifEmptyList.

Now that elm-tools/parser exists as a nicer alternative to regular expressions, I'd rather not couple the public-facing API to Regex. (Internally, though, I'd rather not port that email regex to a Parser... 😅) So I'm gonna close this.

Thanks again!
