Made sure that the SoapUIProjectSelector checks whether there were a previous testCase selected instead of just overwriting it with the first element in the ComboBox as is expected when importing a project.
LOADUI-497 fixed that the the selector sometimes didnt change SoapUI
Runner´s testSuites or cases (weak listeners got lost)
LOADUI-508 opening new project now clears test step list
Merge branch 'hotfix_LOADUI-497' into hotfix_LOADUI-496
LOADUI-496 Re-factored new code and did some styling on SoapUI component.
