* removed the never used start_process() function
* BBBikeAdvanced: use double_fork in reload_new_modules() function

  To avoid zombies. Also, use lexical filehandles in the pipe() call.
* data update
* data update
* fragezeichen2org.pl: sort additionally by distance

  To do this, a little bit of refactoring was done: as an @records
  entry would have got its third element, it was turned into a hash.

* refactored into new function svg2photo
* load_photo() is now capable of handling svg images

  Works only if ImageMagick is installed. A little bit of refactoring
  was necessary and the introduction of the -w/-h options.
* SRTShortcuts: use images in "Add layer" submenu

  Currently images for zebrastreifen, ortsschilder, restaurants,
  kneipen are defined.
* SRTShortcuts: more menu images (bridge for brunnels, VMZ detail net)
* converted HOWTO_edit_bbbike_data document to docbook-5

  This means that the .sgml document was replaced by an .xml file,
  which was initially converted using "osx -x lower -x no-nl-in-tag -E
  9999", and the result was heavily manually corrected.

  The old FreeBSD's docbook.css was slightly changed and renamed to
  docbook5.css.

  Makefile.doc was rewritten completely and does not use any FreeBSD
  makefile includes (but probably needs work so it runs under Linux).

  A schemas.xml for emacs was added, because otherwise nxml-mode (in
  emacs 24) would choose an old docbook schema (v4.x).

  Differences in the html rendering:
  * non-latin1 output is correct now
  * horizontal rulers between sections are missing now (it would be
    nice to get this fixed, but I did not find an option)
  * other slight layout changes, mostly improvements
* Makefile.doc: support also docbook-xsl in Debian
* MANIFEST update
* added link to presse.html
* data update (mainly splitting carriageways of Karl-Liebknecht-Str)
* data update (added missing 'recurring' fields)
* check_bbbike_temp_blockings: don't dump list of future records
  anymore by default

  Instead -v has to be used to dump the list.
* Makefile.doc: added pdf target (experimental)
