Component tracker

[peteryates]

This is a central progress/tracking issue for components based on @tijmenb's list (#3)

Components

• [x] Accordion (too complex, maybe out of scope) #45
• [x] Back link #13
• [x] Breadcrumbs #12
• [x] Details #25
• [x] Footer #35
• [x] Header #17
• [x] Inset text #9
• [x] Panel 8ca545128c
• [x] Phase banner #8
• [x] Start now button #1
• [x] Summary list #48
• [ ] Table (too complex, maybe out of scope)
• [x] Tabs (maybe too complex initially, probably relies on the enhanced content block functionality of View Component) #42
• [x] Tag #4
• [x] Warning text #28

Helpers

• [x] #govuk_link_to #15
• [x] #govuk_mail_to #36
• [x] #govuk_button_to (thinking this should map to Rails' button_to but maybe there's also need for a link styled as a button #36
• [x] #govuk_back_to_top_link #19
• [x] Skip link #20

Other useful stuff

Perhaps this shouldn't be in here, but it's something that's probably useful to every project. Maybe it's better suited to the DfE Rails Boilerplate

• [x] A GOV.UK date format that can be used by Rails' date helpers, eg object.submitted_on.to_formatted_s(:govuk), see example. A PR with this functionality has been submitted to the boilerplate

[rjlynch]

I think we should include a back_to_top link helper. I saw that pulled out into a helper and used a bunch on SE

[aliuk2012]

I think this list should be in the Readme so its more visible which components it does have.

Everything except Table is in. Closing this as table might be a bit involved, opened #53 to address it.
