gracefully handle rooms where 'ssl is required'

[lloyd]

upstream IRC library silently fails when trying to join rooms where ssl is required. that means no callback, and futher rooms we attempt to join are not joined. yuck.

Offer an upstream patch, and consider twaddling irc to connect over SSL.

oh, one such room is irc.mozilla.org #release-drivers

/cc @kennyluck

until this issue is resolved, #release-drivers will not be logged.
