Issue:
Font styles and weights naming
Hi! I’m testing Tailwind, and have a question about some class naming.

I was expecting these rules to be declared by these classes:
- `font-style: normal` from `.font-normal` or `.normal`
- `font-weight: regular` from `.font-regular` or `.regular`

But Tailwind works this way:
- `font-style: normal` from `.roman`
- `font-weight: regular` from `.font-normal`

I find that very misleading, because:
- When I encounter `.font-normal`, I think about `font-style: normal`, not about `font-weight: regular`
- If I’m coding a website not using a latin alphabet (let’s say Chinese or Arabic), the word `roman` does not resonate in any way with `font-style: normal`.
- Also, `roman` makes me think to [`list-style-type: lower-roman`](https://developer.mozilla.org/en-US/docs/Web/CSS/list-style-type) (or `upper-roman`).

What are other people views on this? Can you consider to rename classes in a further breaking update?


Discussion:
You can change `.font-normal` to `.font-regular` in your own config if you like; we chose the font weight names based on this document from the W3C:

https://www.w3.org/TR/css-fonts-3/#font-weight-numeric-values

The `.roman` situation is admittedly more annoying. We wanted `.italic` for italicized text, so similarly wanted a single word class for undoing italic text at different breakpoints. We bikeshedded over `.unitalic`, `.no-italics`, `.not-italic` and others before eventually settling on `.roman` because "roman" is the word typographers use to refer to upright text vs. italic text:

https://en.wikipedia.org/wiki/Roman_type

I'm not opposed to changing that name but I don't want to use a name that uses the `font-` prefix because it would be the only class that isn't a font weight or font family class that starts with `font-`.

Having not thought about the `roman` stuff in like 5 months, I think I'd be happy with `.not-italic` if that works for others.
