changed RawTester.test to accept a testname

RawTester.test can now accept a testName instead of defaulting to one based on the millisecond time stamp. This is similar to how RawTester.verify works.

This looks good to me, but is missing a unittest which checks that the correct directory is created. Happy to merge, once you add that test. Thanks!

Thanks for pointing that out, my apologies. I've added one that will utilize Icarus to check the RawTester.test(testName) option

Thanks for adding the test! I made it work with treadle which is the easiest default. Icarus does not seem to be required for us to test this functionality.
