Remove coffeescript-growl require.

This does not work with CS 1.6, nor is very general.
Add new-line to package.json template to match "npm install --save" output.
Add mocha and coffee-script as default dev-dependencies.
Use local binaries.
Let "make test" run mocha.
Generate an empty test file.
Let 'make jumpstart' run "npm install" to (to install the dev dependencies).
Generate the directories before attempting to write to them.
Use "git add ." instead of "git add *" because that command fails with gitignore.
Ignore /node_modules.
