Show all test failures during make test

In development I prefer to run nosetests with -x to exit on the first
error/failure, but for make test we should show all failures. This threw
@Lucretiel for a loop, e.g. Run nosetests directly if you want to
influence it's behavior further.
add test_all target that doesn't stop on first failure
Merge branch 'master' of github.com:gittip/aspen-python

make two test targets:
    test runs tests with stop-on-first-fail
    test_all runs *all* tests, no stop-on-first-fail
revert back to test instead of test_all
Make it clearer what two tests are doing; #153

Stop doing unnecessary decodes.
Fix bug in virtualenv construction

The quotes in --prompt="[aspen] " were getting escaped by fabricate and
were bleeding through into the generated bin/activate script in the
virtualenv. I don't know why I didn't notice this before today. My best
guess at this point is that I simply wasn't running `make dev` but only
`make build`, which doesn't create a virtualenv.

Implement workaround for #190

@pjz has a fix for fabricate but we can't wait for that and I don't want
to fork fabricate in our repo if we can help it, which we can.
Soften the blow. Not *deprecated*. :)
Remove obsolete test; #192

This test depended on behavior of the tornado renderer. Now that that's
been moved out into a separate module, this test should theoretically go
with it. It doesn't belong in here anymore, at least.
