9/15 Update: More bug fixes

This update fixes several bugs which were preventing full progress through Chapter 1, and also tweaks combat balance slightly.   A player should be able to fully progress through the game now (the first 4 chapters).

*  Fixed a bug which prevented movement between RZ2 and RZ1.

*  Fixed a bug which caused infinite Seal Guardians to spawn.

*  Slightly adjusted the Physical and Magical Evade formulas.

*  Slightly adjusted the stats of a few enemies.

*  Removed a bush in RZ1 which caused a player to get stuck if coming from RZ3.

*  Reduced the size of the bookshelf zones in the Library in Rainbow Town, to reduce the chance of 2 triggering at once.

*  Removed the red bar which appeared above the character's head after loading a saved game.

*  Fixed an issue with the cave lights not working properly after loading a saved game.
