Automated ETS tests

All ETS projects are tested on an hourly basis.

Testing ETS involves the following steps:

• Checking the entire ETS trunk out of the SVN repository.
• Building the projects; this includes compiling C extensions.
• Testing the projects, i.e. running the unit tests.

Note: This is a short term solution to publishing test results. In the long term, we are planning to use Buildbot to run tests on multiple architectures.
