Integrate bulk processing tool

[dracos]

Transferred from mysociety/mapit-bulk-processing#1

• Design lookover of process
  • Form fields (column select, skip bad rows tickbox, pick which area types list, email/description)
  • Error messages
  • Table display
  • You'll get an email/download your CSV pages
• Advertising this elsewhere on site => Advertise data mapper on the site #46
• Copy for each step of process, success email

Just to note this is live at https://mapit.mysociety.org/bulk/ - I reused the front end code from accounts, so that looks okay, but the things above are the outstanding things potentially left.

Here's a draft for some copy and the success email, plus error messages.

I've probably made some wrong assumptions so feel free to change it!

Notes on the visual elements:

• The file input with the text input styling (because we’re re-using the .account-form__field styles) looks a bit funky, but I guess it's still usable. I can spend a little time fixing this if you want. => Bulk: Improve file upload field #47
• "Next" buttons should have btn--primary not btn-primary class. (Sorry, this isn’t a Bootstrap site, despite the classes looking kinda similar.)
• I wonder whether it'd make more sense to swap the vertical order of the "Now tell us where the postcodes are" and "This is what your file looks like" sections? So, first you show them what their file looks like, and then you ask them to make a selection from the dropdown and click "Next".
• I’d probably put the "Prev" and "Next" buttons on the same line, in that order (rather than wrapping the "Prev" in a <p> after the "Next" button).
• Also, any chance we could make the personal_details-email input a <input type="email"> rather than <input type="text">?

I vote for this (though you'd need to only show a few lines I think - the depth it is at the moment, you'd run the risk of the text underneath being overlooked).

Most/all the above integrated, and live, moved bits to new tickets, considering this closed.
