soju support

[vaaleyard]

I've always used ZNC for IRC bouncer (tbh never tried to switch), but I'm aware there are other options like soju.

Not sure if people use it, so if you do and tried to use with dex, please leave here your feedback. If it's not working, I'll probably need to add support for it.

(posting for posterity, we talked about this in the irc channel)

I personally don't plan on using bouncers (i.e. I'm comfortable with missing messages when I'm offline), so I have no opinions on additional support.
