* new deployment target "prepare"

  This is the combination of four prepare-* targets.
* radrouten.t test: test at least _one_ link

  In "smoker" mode (or with -test-all switch) all links are tested;
  this is what the old -doit switch (now gone) did.

  The test script obeys the BBBIKE_TEST_SKIP_MAPSERVER env variable,
  and uses the check_cgi_testing check.
* data update
