* add normalizeScreens function
This will allow us to normalize the various kinds of inputs to a stable
version that is consistent regardless of the input.
* use normalized screens
* add dedicated test for new tuple syntax
* make test consistent with other tests
While working on the normalizeScreens feature, some tests started
failing (the one with multiple screens), while looking at them I made
them consistent with the rest of the codebase.
* add test to ensure consistent order in screens output

* use String.raw for css escapes
This will allow us to write code like:
```css
.mobile\:font-bold {}
```
Instead of
```css
.mobile\\:font-bold {}
```
Which resembles "real" css way better in our tests.
* use String.raw in integration tests as well
* move `./tests/jit` to `./tests`
* make tests consistent
Abstracted a `run` function and some syntax highlighting helpers for
`html`, `css` and `javascript`.
