* bbbikedraw.t: changed internals for skipping testing rendering
  modules

  Also introduced the environment variable BBBIKE_TEST_FOR_LIVE.
* set BBBIKE_TEST_FOR_LIVE in deployments
* httpd.conf.tpl: preload more in ModPerl::Registry operation

  (But using mod_perl is still not recommended)
* removed code for denying specific IP addresses in the
  bbbike*.cgi.config files

  Nowadays the Perlbal's throttle plugin is good enough for this
  task.
* cgi: removed some unused (global) variables
* data update (very minor)
* ups, a stray newline
* removed unused imagemap handling code from cgi

  This never really worked, and anyway modern browsers don't have
  support for self.status anymore.

  The old imagemap creation code was moved to the new module
  BBBikeDraw::ImageMap.
* bbbike_tmp_cleanup.sh: remove also cache files created by cgi-test.t
