Renumber the test scripts into themed ranges

    t000x  the ground the suite stands on: git version, html validity,
           the cache
    t01xx  page content, one script per page
    t02xx  features that cut across pages: filters, submodule links,
           dates, limits
    t03xx  defence, the security regressions and the $HOME promise
    t04xx  the helper tools under tools/
