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
Tell people to download a proper deployable Hubot
Keep supporting '@All' for HUBOT_HIPCHAT_ROOMS

Fixes #52
Version 1.1.1
Don't error on more complex room JIDs.

Room JIDs can contain many other characters, so loosen the regex and
rely on the domain part (conf.*).

Also remove the author.room value for private messages since it doesn't
make sense and was calling the wrong function anyway.
Allow @mention name to be used in 1-1 messages
Version 1.1.2
Switch reply to use mention name

When replies it'd be good to use the user's real mention name (or @ name), not a guess based on their real name.
