v2.3.4. Bugfix. Improvement.

- v2.3.4 January 8, 2013
	- Better handling and detection of failed watching operations
	- Better handling of duplicated events
	- Watching is now an atomic operation
		- If watching fails for a descendant, we will close everything related to that watch operation of the eve
	- We now prefer the `watch` method over the `watchFile` method
		- This offers great reliability and way less CPU and memory foot print
		- If you still wish to prefer `watchFile`, then set the new configuration option `preferredMethod` to `watchFile`
	- Closes [issue #30](https://github.com/bevry/watchr/issues/30) thanks to [Howard Tyson](https://github.com/tizzo)
