corrected typos in POM.XML files
Removed overzealous optimization from driver. The optimization avoided
clicking the setup & execution links if the test results were already
visible. However, in some test scenarios, the execution link must be
clicked, even if a results message is already displayed, because the
results may change based on a parameter set through the link, for example.

The test driver now strictly adheres to the following sequence for each
test case:

1) Access page
2) Click setup link (see: TestSetupLink.java), if present
3) Click execution link (see: TestLink.java or TestButton.java), if present
4) Collect test results
Moved to latest selenium level 2.43.1. This seems to fix an intermittent
problem that sometimes occurred during test execution.
