The main change is to add support for Spoon to take screenshots.

Once we are happy with using Spoon we can add code that automatically
takes a screenshot when tests fail. This may help us debug some of the
problems we encounter running the tests on various devices. Using Spoon
exposed a limitation/key behaviour of ActivityTestRule that references
the intended Activity under test. To account for this behaviour I
restructured DownloadTest so it simply tests the download, rather than
reading the contents of the file.

I also discovered that the tests would fail on wide-screens as the Home
menu option moves from the overflow menu to the main menu. I've modified
one test to cope. Again, once we're happy with this approach (which
involves a little extra code) we can revise all the tests so they can
run equally competently on various screen sizes.
