This changes the output format of the JSON webservice. Results are no longer
wrapped (twice) in an object. For example, the request

    /checkSyntax?variant=AB026906.1:c.274del

used to return

    {"checkSyntaxResponse": {"checkSyntaxResult":
      {"valid": true, "messages": {"SoapMessage": []}}}}

and now returns

    {"valid": true, "messages": []}

We also use "soft" input validation.

This removes the need for the top-level package_root function. On the
way we also remove the top-level is_test function that was obsolete.

This is more in line with common practice. Furthermore, the web.py
built-in HTTP server only looks there (hard-coded unfortunately), so
this is the only way to easily run Mutalyzer without a separate
webserver.

The actual conversion of the repository was done using svn2git [1].
