disable test

I have been told that the tests currently do nothing, and they take time.

To fix this issue, we will want a variation on jgplsrc/test/test.ijs which exits with a non-zero exit code if an acceptance test fails.

Acceptance tests should probably be all test/*.ijs files except the test/*t.ijs files. (The *t.ijs files are timing tests, measuring relative performance of various parts of the system - that won't work very well for code meant to be deployed on different completely different machines.)
