Yet another levels update by Marek.
Changelog:
�I fixed some minor flaws and tried to give each of
the maps an original title. The latter was kinda difficult, because most
of the maps didn't really have a theme, (like the bridge or the castle)
so I had to make up their names; a task in which I maybe failed in some
parts, but at least it's better than just numbers.�
