1.0.2 Fixes

1.0.2 fixes a few things in the late and postgame.

• Mirror room in the Upper Halls had a broken transfer event that lead back to the Skull Beast's boss room instead of the Skull Guard's after completing enough floors
• Between the two phases of the final boss, the game would continue to phase 2 even if the player lost in phase 1. This was due to messed up event nesting.
  
• After the credits and the final timer and run count, the player now teleports correctly instead of remaining transparent and without menu access. The slightly altered post-game "Welcome to Purgatory" message was also not triggering properly, now it should.
• Added a "Disable Mouse" plugin so only keyboard controls work now, as leaving the mouse on the game screen could mess with enemy selecting in battle.
