Issue:
Add overflow-x-hidden and overflow-y-hidden
They're useful because sometimes you want `overflow-x-hidden overflow-y-auto` (the default `overflow-x` when `overflow-y` is set to `auto` is also `auto`).


Discussion:
Yes! I just had to manually add these to a site I was working on yesterday. I guess @adamwathan will be okay with a PR that includes this as well as tests for them (probably a PR for the docs too).

@benface do you wanna take care of it or should I open the PR myself?
@hacknug Actually after posting this issue I realized this is doable already with the existing classes. Just do:

```
overflow-hidden overflow-y-auto
```
or
```
overflow-hidden overflow-x-auto
```

Because `.overflow-hidden` is defined before the `.overflow-x-*` and `.overflow-y-*` classes in the CSS, it is overridden by them. So with the snippets above, you effectively get `overflow-x: hidden; overflow-y: auto;` and `overflow-y: hidden; overflow-x: auto;` respectively.
I think these should be in the framework 👍 Happy to look at a PR!
