  Changelog:
  16.07.17 - Merged several PR from others (Typo, screenshot, documentation, mesecon support, bugfix).
             Added buttons to move stations up or down in the list, independent on when they where added.
+            Fixed undeclared globals.
+            Changed deprecated functions set_look_yaw/pitch to current functions.
  22.07.17 - Fixed bug with locked travelnets beeing removed from the network due to not beeing recognized.
  30.08.16 - If the station the traveller just travelled to no longer exists, the player is sent back to the
             station where he/she came from.
