v2.0.0. Improvement.

- v2.0.0 April 5, 2013
	- We no longer alias split off projects, you should use them directly
now
	- Killed `(git|node|npm)(Command|Commands)` functions, use
`spawnCommand` and `spawnCommands` instead
	- `replaceElementAsync` now executes tasks in parallel rather than in
serial
Added npm badge to readme
