[Issue(s) #42]
Merge pull request #42 from sopel/patch-1

Added hint to omit '@hubot' in 1-1 chat.
Setup instructions improvements
Latest Hubot
Explicitly require node-expat 1.6.1 to fix #46
Bump suggested version
Use 'All' instead of '@All' to join all rooms.

@All is misleading since it implies some sort of @mention behavior.
Layout tweaks
v1.0.11, with Wobot 0.8.0
Ignore node_modules
Get @mention name automatically (fix #7 and #49)
Don't depend on coffee-script (hubot gets it)
Version 1.1.0
Fix up package info a bit
Switch to new Procfile style in README. Fixes #50
