Add regression testing (#38)

* Added latest bugfix release of LibGEOS for this minor version.

* Added regression testing.

* Added tests for old issues, added tests for invalid geometry that crash on Windows.

* Commented out test runs.

* Used incorrect Polygon on which an error should be thrown.
