Change file paths to be __dirname relative, so that bin/hubot can be run from any PWD
Fix loading top level scripts from a hubot instance created for deployment
Allow hubot to react on events

Events might get triggered by scripts.

For example: You have a script, which can trigger and event that some one committed to a repo. This script can be used by anyone, but the reaction should be different by every company. So it's possible to trigger a build, or just post a message in chat.

As a plus with the same event triggered by different scripts, so it wouldn't make a difference if you commit into github or just another (maybe SVN) repo. But other scripts can rely on that 'commit-received' command and act the same way.
added docs for event system
Command line option for extra scripts dirs
Check for null when there are no images

if I did something like "hubot image me ablederfl33wo", I would get an error like:

/opt/hubot/scripts/google-images.coffee:47
      images = images.responseData.results;
                                  ^
TypeError: Cannot read property 'results' of null

Use GET to get Campfire rooms, not POST

There's no need to use POST when fetching a room from Campfire, and
doing so risks running up against Campfire's POST rate limit (50 POSTs
in 5 seconds).
