NailGun is currently listed as being "pre-alpha" quality. I'd like to push NailGun forward so that it is more viable than that. I'd like to make NailGun high-quality enough that it can be used by third-parties without hesitation. What are the qualities of a high-quality product?

• Well documented.
• Well tested.
• Stable enough to be forward-compatible with future changes.
• Provides significant utility and is easy to use.

This milestone is much like the "alpha" milestone. However, there are some differences:

• The various entity methods should finally be normalized. (#41) This is an interesting problem that may require several tries to get right, but some good solution should be adopted. If an even better solution makes an appearance in the future, then that's a big enough improvement that it would rightfully warrant a major version bump (e.g. from 1.4.2 to 2.0.0).
• Fix other issues that will affect NailGun's API. For example, #135 will definitely affect the API.
