CSS @import: Make url optional for local files #612

Currently if you want to import a local CSS file you need to use syntax like this:

@import { url('~/your-style.css') }

This seems a bit silly because:

• There are technically no URLs for local files.
• The browser's @import does not require “url” (see https://developer.mozilla.org/en-US/docs/Web/CSS/@import)
• This syntax can mess up CSS tooling (see Minor css fix sample-Groceries#7)

I would like to request the syntax below to import a CSS file within my app:

@import { '~/your-style.css' }

Or even better drop the curly braces too:

@import '~your-style.css';

Thanks!
