Bumped log4js to the 0.4.x version to allow restoring the console (see #5).
Also some minor edits to the readme and a sample config file for the tests.
Not all the tests passed for me - let me know if they don't pass for you and I'll help fix them, otherwise I assume it's to do with the IDs being used in the tests?
dev dependencies, readme tweak, sample config
upgrade log4js, closes #5
