Wagtail-resume

Changes:

- Fix Weasyprint background color
- Change to smaller fonts

- Fix pdf generation when using fonts with spaces
- Fix meta url

- Make the image 200px

- Use page id when using weasyprint

Uses reverse in template now, enabling url importing to have a different pattern than '/resume/'

Breaking changes:

- PR 21 introduced Weasyprint which requires adding urlpatterns for this application. Otherwise, pdf generation won't work.

Minor changes:

- CSS has been changed, primarily making fonts smaller.

Dropped CI for django22 and python36. This package targets >django 3.0.0 and >python 3.6 now.
