[ANN] Clojars 109 - two-factor auth support & deploy token improvements

[Toby Crawley]

Howdy folks!

We just released Clojars 109. The changes since 105 (the last version
I announced here) are:

- An endpoint to receive deploy token compromise reports from GitHub:
this will disable the token and email the owner when GitHub finds a
deploy token in a commit. This hasn't been fully implemented on their
side, so isn't yet active.
- Deploy tokens can now optionally be scoped to an artifact or group
- Optional two-factor authentication support - see the wiki for
details: https://github.com/clojars/clojars-web/wiki/Two-Factor-Auth

A big thanks to André Eriksson (https://github.com/aeriksson) for
fixing some visual issues with deploy tokens, and to Daniel Compton
(https://github.com/danielcompton) and Paul Stadig
(https://github.com/pjstadig) for reviewing the two-factor auth
changes.
