Add Custom Fields to Test Runner

We need the ability to add custom fields to the Test Runner.  When we test for a release, new builds are continously created and are used by various departments/individuals to test against.  We need to record which build was used during each test run.  We also need to be able to record which environment the test was executed in.  Our test environments are extremely dynamic in that db schemas are refreshed frequently, new builds are installed, and various browsers are used. This information is needed for each test run for tracking and performing root causes analyses.
