Authl v0.4.6 released

Wow, it’s been a while since I’ve worked on this stuff, huh?

Anyway, IndieAuth validation rules have changed for the better, so Authl has been updated accordingly.

There’s a few other changes as well:

• On IndieAuth profiles, p-pronoun is treated as a fallback for p-pronouns
• The Flask templates add some rel="nofollow" in some appropriate places
