remove has_test_pod, has_test_pod_coverage tests (they are "extra" anyway)
remove "extractable" test
add in all the standard tests that ought to work
remove "use vars" and all global variables
use a list of flags for metrics to skip (maybe make configurable, later, to enable extra/experimental?)
the list of metrics will change again in MCA 0.88
Test-Kwalitee-1.09

    - the has_test_pod, has_test_pod_coverage tests have been removed - they
      are classified as 'extra', and have been largely considered to be a bad
      idea anyway (these are often shipped as, and ought to be, in xt/)
    - the extractable test has been removed, as it does nothing in dists
      before there is a tarball present
    - new tests have been added: all standard kwalitee tests that can be run
      on a bare distribution without a tarball
