Subject: [PATCH] Trigger tox from package.json, if necessary.

This patch adds several fixes to improve karma test handling.

* A postinstall hook was added to package.json, which tests for
  the existence of .venv. If it is not found, it will invoke
  tox -e py27 --notest.
* Both karma.conf files were taught to automatically detect the
  directories in which the xstatic dependencies might live, and
  pick the appropriate directory.

postinstall was chosen, because setting up a virtual environment
is likely to be useful for more than one type of npm job.
