What would you like to happen?

Please enhance the unit test dialogue so that

1. There is a Browse button enabling the navigation to the location and selection of the pipeline
2. There is a Browse button enabling the navigation to the location where the unit test is to be saved
3. The HOP_UNIT_TESTS_FOLDER variable is available by default (i.e. it's shown as ${HOP_UNIT_TESTS_FOLDER}
4. The window caters for the use of Parameters in addition to Variables.
