`reset`

The `reset` mixin should allow to set default values for multiple properties at once. The "default value" depends on the property (or properties) being reset: it can be `auto` for `width` but `1` for `opacity`.

```
reset([property [, property...]])
```

This function should accept a list of zero or more property names, as literals or as strings. Property names can be "real" properties (ie: `height`, `font-size`) or shorthands which may expand to more than one "real" property. In the following example, `size` is a shorthand property, while `font-weight` is an actual CSS property:

```stylus
body
  reset: size font-weight
```

```css
body {
  width: auto;
  height: auto;
  font-weight: normal
}
```

We should be able to use `reset` multiple times on the same block and also with no arguments (in this case, nothing should happen). 


`reset` should be able to handle `!important` and live together with other mixins:

```stylus
body
  reset: box-shadow margin !important
```

```css
body {
  -webkit-box-shadow: none !important;
  box-shadow: none !important;
  margin: 0 !important;
} 
```

More?

Notes:

* Some versions of IE *need* an additional `background-image: none` for the `background: none` reset. 
* `reset: list` and `reset: list-item` should reset lists default styles on `<ul>` `<ol>` `<li>` `<dl>` `<dt>` and `<dd>` elements: `list-style` `margin` `padding`.
* Does it makes sense a: `reset: counter(name)`?
