We'd like to move from our fork of 2016 Django Materialize to django-materializecss-form.

This also involves upgrading from v0.100.2.

Upgrade Materialize

• Handle breaking changes between v0.100.2 and v1.0.0 https://github.com/Dogfalo/materialize/blob/v1-dev/v1-upgrade-guide.md
• Handle breaking changes between v1.0.0 and v1.2.2 https://github.com/materializecss/materialize/releases

Upgrade Django helper

• Switch template filters to new set
• Test all the forms manually
• Check that things are working in the areas we customised on the 2016 repo
• Eliminate the dependency and document the change on https://github.com/BirkbeckCTP/django-materialize
