Refactoring tests and moving code to common module

1. All tests have been converted into regular command-line mocha
   tests (instead of running in the browser), and the deployment
   script has been changed to automatically fail any `--new`
   deployment which doesn't pass.
2. Several small class (e.g., `Logger`) have been moved into a common
   module, `crafting-guide-common` so that they may be shared between
   the client and server.
