start working on tests

+ Current setup will likely not last long, just a stopgap until I figure
  out how I want to build each testcase etc.

  Probably dir based, but I'll probably add some scripts that generate
  the build rules for each test case (or binary?). Also, should probably
  put ouput files in a build directory and keep the source clean, but
  again, good enough for now.

  Will have to start implementing more extensive tests, and probably
  come up with some way to compare textual output etc.
