[Add tests of caps from the future that have non-ASCII characters in them (encoded as UTF-8). The changes to test_uri.py, test_client.py, and test_dirnode.py add tests of non-ASCII future caps in addition to the current tests. The changes to test_web.py just replace the tests of all-ASCII future caps with tests of non-ASCII future caps. We also change uses of failUnlessEqual to failUnlessReallyEqual, in order to catch cases where the type of a string is not as expected.

 Impose micro-POLA by passing only the writekey instead of the whole node object to {{{_encrypt_rw_uri()}}}. Remove DummyImmutableFileNode in nodemaker.py, which is obviated by this. Add micro-optimization by precomputing the netstring of the empty string and branching on whether the writekey is present or not outside of {{{_encrypt_rw_uri()}}}. Add doc about writekey to docstring.
