Support for every property (#144)

- Support for all properties
- Shorthand mixins for margins and paddings
- Support for custom properties
- Clearer way to declare `!important` rules: `@include rfs(1rem !important)` instead of `@include rfs(1rem, true)`
- Switched to mobile first approach, still possible to switch to the `max-width` media queries if needed
- Configuration variables are changed:
	- Base font size -> Base value
	- Font size unit -> Unit
- `responsive-font-size` property changed to `rfs()` function (see https://github.com/twbs/rfs/issues/116)
- Dropped `responsive-font-size` mixins
- Dropped Less 2 support since we had to work with lists
- Prevent generation of `/test/expected/main.css`
- Additional tests for new implementations
- Cleanup npm scripts examples
- Code examples in `README.md` are grouped by processor and collapsed
