Feature request: Allow exporting other variables/columns #53

The situation we have is that the test suite name provides context for the test case. Currently exporting a test suite with several sub-suites results in testcases with no context. We would be greatly helped if there was an option in the Offline Test Execution Export to add extra columns to the export like "Test Suite", "Priority", "Tags" and so on. This would be useful in very many ways. Keep up the great work!
