Add test progress to Test Execution

When Test Planning is viewed, the user is able to see the execution progress in each folder/ sub folder. It would be really useful if Test Execution would also be able to show this kind of progress. Due to the complex nature of our folder structures within projects, the colour breakdown of test status is a really useful way for us to track where we have outstanding test cases that need to be completed. This change would be a very useful tool rather than having to navigate to test planning to see this information and then back to test execution to carry out the test cases.
