Mainly reworking of Gruntfile.js to support "buildEnv" options. Make
Google Analytics optional. Allow for post-processing by writing output
either to "tmp" (if post-processing is needed) or straight to "out" (if
it isn't).
Before making partials...
Refactor templates into partials to allow different default layouts for
hbs, html or markdown. Move my code from the Gruntfile into my (first
ever!) node module. Add some logging. The Google Analytics and jQuery
inclusion flags are now working.
