Simplify dependencies

Removes firepit and its dependencies, and instead uses express to run a
simple static server to demonstrate how to use gozer.

Closes #6.
Only publish compiled javascript

* Adds a prepublish task that compiles the source coffeescript files into
javascript.
* Makes coffee-script a development dependency
* Cleans up .gitignore following the unfirepitification
* Adds a .npmignore so we don't publish anything we don't need.

Closes #7.
Bump to 0.0.3

Following dependency cleanup and changing what exactly we're publishing.
Require coffee version in tests

So we don't have to have the compiled version for tests to work.
