Better way to handle accounts.email-verification.blacklist-regexes?

Sorry for the poor title, please adjust as needed.

Would be nice to be able to read a list of emails to block from a file, or something. If you want to keep something like disposable_email_blocklist.conf in your ergo.yaml, you end up with literally 1000s of lines and it's a pain to keep up-to-date.

Aside: the example of regexs should actually be like: .*@example\\.com

Good suggestion! I'll take a look at this for the next release.

@progval noted that YAML includes would be ideal for this, however AIUI neither v2 nor v3 of our YAML library supports them. Switching to another library is risky in terms of compatibility breaks.
