added full compatibility for wrap-around levels in EM engine

The previous support for wrap-around levels in the EM game engine was
some sort of "idealized" implementation that lets the player wrap
around by moving horizontally on the same vertical level position
forever (which results in truely infinite wrap-around levels).

existing EMC levels unplayable and/or unsolvable. (Examples are
level 80 of "Ruppelmine 3" or level 34 of "The Exception 2".)

Instead, the original game engine caused the player to step one
vertical position up or down when leaving the playfield at the left
or right border, which is required by the mentioned example levels.

improved startup speed by optimizing parsing of parameter values

Commit bd5cd062 (that introduced event actions for global animations)
also added a nasty performance bottleneck due to complexity of parsing
event action parameters, which slowed down program startup phase quite
significantly. However, in most cases these parameters just stay at
their default values, so checking for that default value first results
in massively speeding up this part of the startup phase.

stored undo tape.
