Made ant target 'junit-test' produce a report like all the other

junit ant targets. The report is useful because for a test class
with many sub-tests, the report clearly explains which sub-tests
failed. Unlike other ant junit targets, this target also produce
a plain text report. The plain text report is useful for running
a single test in a loop until it fails.

Clarified the help message for the 'junit-test' ant target.
