Add `proxy` config option to server (IRC), teams, telegram, and mumble
sections. IRC defaults to false (preserving current direct-connect
behavior); all others default to true. The `derp.http` module now
accepts `proxy=True/False` on urlopen, create_connection,
open_connection, and build_opener -- when false, uses stdlib directly.

TeamsBot adapter exposes the same plugin API as IRC Bot so ~90% of
plugins work without modification. Uses raw asyncio HTTP server
(no MS SDK dependency) with HMAC-SHA256 signature validation.
