Added some performance & usability improvements to the driver. You are now
able to run a subset of the tests by specifing the test.module parameter. If
this parm is specified, the driver will execute all test cases whose name
contains the specified string. Also, sorted the parameterized test case list
by page in an attempt to achieve locality of access performance
improvements. Added code to only click the page link when the page actually
needs to change. Switched the default web driver to HTTPunit, as it executes
so quickly. Results of the performance improvements: 32:40 min Firefox with
no improvements, 19:40 Firefox with perf improvements, and 5:40 min HTTPunit
with performance improvements.
