* Move test suite related stuff from "src/" to "test/".
* Fix "test.sh" to search for libfaketime libraries in the right place.
* Split up Makefile into two separate Makefiles (one for the main
program and one for the test suite).
Test cases should go in another directory for the sake of clean code
separation. This will also facilitate the creation of proper Makefiles.
