Avatar customization

[laughinghan]

Branching out from #42, I'd love to be able to choose to use, say, robohash.org/ instead of avatar.adorable.io because I'm totally creeped out by the weird squished faces that avatar.adorable.io generates, whereas I welcome our robohash overlords. (Someone who really hates happiness might prefer GitHub's identicons, etc.)

While we're at it, we should let you disable them entirely so the Slack bot user's default icon shows up.

So something like:

"avatar_url": "https://robohash.org/$nick.png"

and

"avatar_url": false

to disable generated avatars.

(What if by some stroke of evil genius, an identicon service provider (ISP?) requires the string '$nick' somewhere in their URL? Well their evil plan is foiled, because we can just percent-encode the dollar sign.)

Ooh also, you know what would be cool, you can set metadata for your nick on NickServ (/msg nickserv set property avatar http://example.com/avatar.png), we could query for that when someone joins and use it if present

Maybe that would be a totally useless feature

I like the idea of something like "avatarUrl": "https://robohash.org/$username.png". Would you want to try and send a pull request? I think the NickServ feature might be a bit too specific .

Robohash was nice though, cool find.

Same here, very odd faces indeed, would rather disable an avatar altogether if possible instead of having this weirdness.

I don't have time to implement a configuration option just right now, but if anyone's interested in giving it a shot the URL is specified here: https://github.com/ekmartin/slack-irc/blob/master/lib%2Fbot.js#L237
