Merge pull request #114 from ceefour/testtsv2

Improvements for preparation to separate test data into plain text files
Move test fixtures into TSV plain text files.

Test data for RelEx and Stanford are moved into TSV files.

The Test classes (`TestRelEx` and `TestStanford`), in addition to having most of its content factored out, also had unnormalized line endings, so to Git these classes look replaced entirely.

The entirety of test data now reside in these `.tsv` files. I think the format should be self-explanatory just by looking at it.

Ant build and tests still work.

@linas I hope this is acceptable.

Fixed #103.
