PR# 14872 Testing tool collected issues

I've used the wizard to create a new test and here are my remarks:

1 - you are asked to choose a cluster to save your test class, however there is no option that I saw to create a new cluster.

2 - the name of the test is not properly validated resulting in a test that does not show up in the testing tool if you did not prefix it with `test_'. I would rather remove this convention and use the indexing clauses to say whether or not a routine is a test routine.

3 - When running all the tests, it switches to the `Execution (background)' tab. If it fails you get just an icon for status, I would prefer a text. The icon could be inserted in front of the name of the test. Moreover double clicking on the icon does nothing, I expected to go to the `outcomes' tab where I can see why it failed.

4 - There seems no way to delete an outcome.

5 - The view combo box content is definitely messed up on Windows. This is because it uses tabs and the tabs are rendered with a square.

6 - When executing under the debugger at least, this gets printed on the console:
 (eiffel_test_interpreter - Version: 0.1

7 - The content of the `last executed' column is right aligned whereas the label is left align. This is confusing and I personally prefer that everything is kept left aligned.

8 - Instead of just `New' I would say `New test'.
