First Patch

Some improvements were made in this patch:

• Changed UI during game session. Previous was too small and players couldn't see easily the vials.
• Added explosions when lighting  hit a building
• Augment chance ratio for lighting to hit building
• Fixed navmesh for tornado
• Restored credit UI
• Added fading UI at the end and close the app ( before player had to do alt-F4 since there is nothing implemented after the simulation)
• Reduced play time, because 90 sec was too long for the game-play offered by the game.
