* data update (minor)
* renamed BBBikeCGI*.pm to BBBikeCGI/*.pm
* data update (events)
* data update (u.a. some changes in Karlshorst)
* moved temp_blockings_tasks task bbd_to_existsid into own file

  This task was not temp blockings-specific anymore. It's now
  an own script named bbd_to_sourceid_exists.
* new: bbd_to_osm_watch_list
* new Makefile target for creating osm_watch_list*
* data update (systematically added osm_watch directives from
  old bbbike-aux file)
* bbd_to_osm_watch_list: error checking
* MerkaartorPlugin: always use the currently visible region
* data update
* cgi: fixed one "Harmless?" warning by rebuilding street dependents
* brb.html-tpl: do not rely exclusively on <base>

  It seems that some proxy software (e.g. the one used at bund.de)
  does not handle <base> correctly, and gets the .css and .js links
  wrong, causing 404 errors. The workaround is to not use relative
  links here.
* data Makefile: new target osm-watch-lists
* data update
* modernized bbbike.bat for strawberry-based dist
* require WWWBrowser was missing
* GeoURL plugin: fixed "Sites near" URL

  Just removed the double slash.
* LuiseBerlin plugin: don't use Devel::Peek

  ... require it only, so the plugin also works in limited
  environments (stripped perl distributions without Devel::Peek)
* data update (mainly additions in Potsdam: Hermannswerder, Waldstadt ...,
  but also changes elsewhere: Wilmersdorf ...)
