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.
* Update build process to *not* copy over prerendered pages during a
regular build (only during a `dist` build)
* Add dependency on npm "markdown" package and include it in the
scripts loaded in the default layout
* Update the Item model to be able to load from a *.cg file
* Add an ItemParser to process the `item.cg` file
* Update the general parser to be able to work with HereDoc-style
text blocks
* Add a markdown-specific stylesheet
* Add a sample of the `item.cg` file format (Advanced Crafting Table)
