Towards 1.0

[loicteixeira]

For the last release, @Stormheg asked if we wouldn't go 1.0, and I said not quite.
Once we merge #79 with Wagtail 4.2 support, we will probably do another release, but I still believe it's not quite ready for a 1.0 release.
However, it would be a good milestone to reach, so I'll try to list here was I think is needed (bottom line, it should support default Wagtail features)
Please comment on whether I'm missing something and/or we should drop some issues.

Supporting all Wagtail features

• Add SitemapBuildableView #37 (PR Add SitemapBuildableView #48)
• Support S3 server-side redirects #14 & Wagtail RedirectView #16
• Unicode characters in slugs #17 (PR fix #17 Unicode characters in slugs #80)
• Does it work with multilingual content?

Bugs

• Build command seems to ignore set language #15 & Build command is not localizing dates #40
• Build fails if using external storage (such as S3) #41

Nice to have?

• Prevent unnecessary admin/wagtail static files from building #4 (I have an idea to fix upstream)

Other

• Implement Wagtail Python Package Maintenance Guidelines #74 & Move to wagtail-nest #78
