- v2.3.0 December 17, 2012
	- This is a backwards compatiblity break, however updating is easy,
read the notes below.
	- We've updated the events we emit to be:
		- `log` for debugging, receives the arguments `logLevel ,args...`
		- `watching` for when watching of the path has completed, receives
the arguments `err, isWatching`
		- `change` for listening to change events, receives the arguments
`changeType, fullPath, currentStat, previousStat`
		- `error` for gracefully listening to error events, receives the
arguments `err`
		- read the README to learn how to bind to these new events
	- The `changeType` argument for change listeners has been changed for
better clarity and consitency:
		- `change` is now `update`
		- `new` is now `create`
		- `unlink` is now `delete`
	- We've updated the return arguments for `require('watchr).watch` for
better consitency:
		- if you send the `paths` option, you will receive the arguments
`err, results` where `results` is an array of watcher instances
		- if you send the `path` option, you receive the arguments `err,
watcherInstance`
