src/irclib.py: Delay sending SASL authstring until given green light

Browse Source 
That means wait until receiving 'AUTHENTICATE +' from the server, which
means the mechanism is supported and we can proceed to send the
authstring.

It generally works anyway, but it's better to follow the standards, plus
old versions of elemental-ircd may crash if we don't do this.
