(- docs) Adding project-meta-information “shields”

Somewhat silly, I'll agree. But hey, accountability on code-quality metrics of *any* kind (test C.I., coverage, whatever) is a good thing.
(- new meta) Adding Travis-CI configuration
(- meta fix module) Forgot to include 'coffeeify' in the package.json
(- fix:#8 meta tests) Fixing testling configuration for browserify 2.x

Turns out, since browserify 2.x doesn't include CoffeeScript support, and I have to use a custom
module to allow for that (coffeeify), testling's default browserify-based build process won't work
for my (CoffeeScript.) tests. Thus, I worked with [James Halliday]<http://github.com/substack> to
put together an alternative build process, using testling's undocumented `"preprocess"`
configuration-field.

This also involves providing a custom TAP-output-producing HTML file; I built this using Mocha's TAP
reporter.

Closes #8.
