Add Char.toInt with tests

[bradurani]

Adds Char.toInt which seems like it should be there based on what's in the other classes. I discovered there's no easy way to map a Char such as '1' to the Int 1. You'd think '1' |> toString |> String.toInt would do it but toString '1' returns "'1'"!
I can't find an easy way to convert a Char to a String at all. I thought about adding a method for that, but I wouldn't know what to call it, since toString is taken.

About getting from Char to Int: Isn't that what Char.toCode is for? (Or at the very least, you could implement your Char.toInt in Elm by using the existing Char.toCode without doing any native stuff as you do in your pull request.)

About getting from a Char to a String: It seems you have overlooked the existence of String.fromChar.

I'm closing this issue.

@bradurani, if you want to propose addition of Char.toInt, please:

• Do so via a pull request to https://github.com/zeckalpha/char-extra. This is the current standard practice of suggesting completely new stuff (rather than fixing existing stuff) for core: collecting it into *-extra libraries first.
• Try doing it without using native stuff. The existing Char.toCode should enable you to implement Char.toInt in pure Elm.

Concerning "Char.toString", see my previous comment.

Makes since. I'm getting the hang of all this. Thanks for explaining @jvoigtlaender
