tahoe-lafs/integration/test_smoke.py
meejah b96122a8ff Adding to the py.test integration tests, this:
- (on travis) installs Tor
 - installs Chutney
 - uses it to build a local Tor test-network
 - set up an introducer on this test-network
 - sets up two storage servers on this test-network
 - proves that one can add a file, and the other can download it

I also mark the two tests that occasionally fail as
expected failures for now
