RHEL6 and older call it python-jinja2, then it's called python2-jinja2.

Fixes #3.

Overview of changes:

 *  Fixed test discovery code

    Most of the code was broken; discovery by id, version printing...
    Now it's still embarrassingly slow, but at least it somewhat works.

 *  Updated MKit for jattool and test suites to v0.0.34

 *  Updated parser, Jinja templats and more for newer shellfu-bash-jat

 *  Added meaningful content to README.md

 *  Added support for showing test/suite version

 *  Changed 'jats' term to 'id' for jats:// test and suite ids

 *  Ensured proper test status from runtest matches qrun (and

 *  Split-off jattool-minimal for testing machines

 *  Changed jats: ids to use double-slash between suite part and test part

 *  Added error message if test has not finished cleanly

 *  Rewrote broken parts of test discovery and identification

 *  Codebase maintenance

Not very useful alone, but already good to read version of a test suite
or test, given that path is passed as well.

Needless to say, the HTML template is still horrible and needs someone
with better HTML/CSS skills.

The Python parser is still not really correct, but at least does not
depend on function names.

Keep jattool as meta-package for easy installations on workstations.

There's no way this would have worked properly; I don't know what I was
thinking of.
