While this raport is from running SDL-client, root problem is in client
common code and affects all clients. This is memory leak when switching
tileset or quitting program.
Most tileset sprites are put to hash by load_sprite() and everything from
hash is freed by unload_all_sprites(). These problematic sprites however are
not got directly from load_sprite(), but they are created with crop_sprite()
from one.
Fix attached
