Working, real unit tests! Woot!!

RapidApp finally has (preliminary) unit tests again. The newly added
unit test (01_basic.t) simply tests proper application startup followed
by fetching a static asset path using the TestRA::ChinookDemo test app.
Even though this test is tiny, it covers a lot of ground out of the gate
because of all the RapidApp internal startup/setup that has to work in
order for it to pass...
