* new development helper: osm2bdd-devel
* osm2bbd improvements:
  * handle secondary_link and tertiary_link
  * ignore place=neighbourhood
* osm2bbd-devel: better handling of missing relation members
* osm2bbd-devel: support for -variant ways
* osm2bbd-devel: removed the -variant option completely

  Now osm2bbd-devel is smart enough to do the "right thing".
* added link to ticket for strassen-gpx segfault issue under FreeBSD
* final resolution for the strassen-gpx.t segfaults

  It's probably an issue with older perls (older than 5.16.x) and
  XML::Twig and large datasets. It depends on the size of the
  generated dataset, the operating system, the perl etc., so segfaults
  did not always happen. But by using a larger test file with the
  -bbdfile option one could force segfaults.

  So the problematic test is just skipped if necessary.
* re-generated some png images without interlacing

  Mapserver 5 does not seem to have proper interlacing support and a warning

    libpng warning: Interlace handling should be turned on when using png_read_image

  may appear (e.g. in bbbikedraw.t test). Instead of fixing old Mapserver, I
  just saved the two images in gimp without interlacing.
* BBBikeDraw::MapServer: avoid a warning

  Check for definedness, not for existence.
* MerkaartorPlugin: support also starting JOSM from cmdline
* regenerated html pages
