tests: Make tests easier to run at a package level

Add a run_tests script.  Move tests subdir to top level.  Force
terminatorlib into path for tests.

As of this commit, all tests pass:

  ~/src/Terminator/terminator$ ./run_tests 
  tests/testborg.py

  tests/test_doctests.py

  tests/testsignalman.py
