Test Files

+ Added some test-alters (init-up, init-down)

Not sure if these are in the format that I want to stick with, but I
needed something for my tests for now (may change later).
Implemented File Listing

Simple version of file-listing which loads all files that have
the configured file-extension. Validated that the test works
and what not. Also moved the test config into the test-env dir
which is where all testing should happen for here on out.
