[Pkg-emacsen-addons] Bug#866396: circe: Update to new 2.5 version

[Matteo F. Vescovi]

Package: circe
Version: 2.3-1
Severity: wishlist

Dear Maintainer,

given that Stretch release has happened, it's now time to get
circe up-to-date again in unstable/sid ;)

Upstream has released, in the meanwhile, v2.4 and v2.5.

Thanks for your efforts.

Cheers.
