Add styled-components import snippets

[selrond]

styled-components is an extremely common import given it's the most popular css-in-js library.
It could look like this: imsc -> import styled from 'styled-components'

@selrond I would like to not add some packages as this kind of imports could be add nearly to every popular package.
Sorry, but I never used styled-components commonly, only for some specific projects.

@dsznajder I understand that, but you already include redux for example - many people don't use redux at all.

@selrond Still redux is more than 3 times popular than styled-components :)
