Feature - 100% Test Code Coverage

Have you ever seen 100% code coverage in a project before?

Yea... neither have I. :P

I installed [PHP_CodeCoverage][php-codecoverage], saw the high score of most of the files, and then became obsessed with reaching 100%.

Anyway, here's the PR that brings us to 100% code coverage in Klein:

Yea, *shit's cray*.
