• Updates the template to take text or html
• A 1px change to icon position :)

Nit: This comment is confusing now, could update to say 'half the height of the circle'

@dashouse would you mind adding an entry for this to the unreleased section of the changelog? https://github.com/alphagov/govuk-frontend/blob/master/CHANGELOG.md#unreleased

Let me know if you want to pair on the versioning side of it.

[NickColley]

This makes sense to me 👍

@igloosi There's no gotcha's hiding with renaming a component I haven't addressed is there?

@dashouse not for this bit, just need to remember to update all.scss file in packages

did you rebase from master, where Ollie removed the link component?
it currently fails with

Message:
    src/globals/scss/govuk-frontend.scss
Error: File to import not found or unreadable: ../../components/link/link.
       Parent style sheet: /Users/janikraner/Desktop/git/govuk-frontend/src/globals/scss/govuk-frontend.scss
        on line 19 of src/globals/scss/govuk-frontend.scss
>> @import "../../components/link/link";

@dashouse I've updated CHANGELOG to reflect changes in this PR. Could you please check I've captured everything.

Our new guidance for updating CHANGELOG is here, I've only just added it: https://github.com/alphagov/govuk-frontend/pull/433/files
