WIP: SSL on IRC connection

[benjaoming]

I thought this would be easy -- but so far, it has just been a rabbit hole of sorts.

So I'm posing my current results.

#496

Issues:

• Messages are not forwarded from Zulip=>IRC, the connection breaks and we get:

  irc_mirror_zulip has left the room (Quit: Read error: error:1408F119:SSL routines:ssl3_get_record:decryption failed or bad record mac).

• No scheduler object, so reconnections aren't scheduled and the whole bridge dies

Hi @benjaoming, are you still interested in working this?

[benjaoming]

@PIG208 - I would be happy to comment/review on any work extending on this, but realistically I don't have time to finish it. I don't think there's anything in this PR that couldn't be taken further.

I'll try to ask around if anyone would be interested in picking it up.
