ERC contribution layer for Spacemacs

Description

Highlight nicks (using erc-hl-nicks)
Image inline support (using erc-image)
Logging to ~/.emacs.d/.cache/erc-logs and ViewLogMode for viewing logs (using erc-view-log)
YouTube videos Thumbnails inline (using erc-yt)
Social Graph for ERC messages (using erc-social-graph)
ERC yank, if pasting more than 5 lines, create a gist for it. (needs to have github layer enabled, or using gist package)
Optional SASL authentication via the variable erc-enable-sasl-auth (using erc-sasl)
Gitter support! This includes clickable issue numbers, inline markdown highlighting, and more (check package doc). Go to irc.gitter.im to get credentials and use erc-tls to connect ( SPC a i E ).
Completion of Emojis using company-emoji (still needs a way of showing, either using the emoji layer or having a proper font) 👏

To use this contribution add it to your ~/.spacemacs

  (setq-default dotspacemacs-configuration-layers '(erc))

It's recommended to install the terminal-notifier gem so that you get notifications via the OS X Notification Center.

erc-social-graph needs graphviz to be installed on your system.
