Updated dependencies, most specifically switched to the new-and-improved coffee-script-redux compiler

The updated dependencies should merit an update, as well as the switch to coffee-script-redux. This compiler is more recent, and is generally considered the better compiler for coffeescript since it follows the standard principles of compiler design.
The test suite still fails, but this was already the case for the current state of the project, so for now I'm leaving it to the original author to fix this.
To reflect the correct information in the buttons, the references in readme.markdown to travis and david should be updated
