Random TestCase option

[fcohen]

The <test> element should have an alternate version that lets TM select a random <run> element. For instance:

<test randomizer="on">

<run name="MyTest?1" ... >

<run name="MyTest?2" ... >

<run name="MyTest?3" ... >

</test>

At run time TestMaker chooses one of the three <run> elements at random.
