KNOWN BUGS

- be more specific in W_Edit::check_buttons (see this function
  for more information)

- when restarting a game (i.e. starting, finishing, starting), the map is
mostly black; Update: somehow the Tiles aren't loaded correctly (_they_ are
black)

- W_Edit::nextStack doesn't work correctly

- file file.h/file.cpp should be File.h/File.cpp! files should have the same
  name as the class, besides file.h is a standard include file!!

- the game flickers during battles etc. Best would be to turn the timer off and
turn it on again during special events like fighting

- MapGenerator: Cities can be next to each other without space! At least 2 squares
  should be inbetween

BUGS TO BE VERYFIED
