Crossing The Sands Updated

Changes in this Version of Crossing The Sands:

• Added tooltips to the spellcasting screen that give a quick summary of what a spell does so you don't have to refer to the manual as often. They'll appear when a spell button is hovered over with the mouse or has keyboard focus.
  
• Made an adjustment to the camera field of view and added a field of view slider to the escape key settings menu. It can be adjusted from 75 to 105 degrees, with 90 as the default, and is a computer-specific setting.
  
• Added more things to the City of Assassins (buildings, furniture, etc).
  
• Changed the ring of swiftness quest reward to be usable by all (was previously Monk-only).
  
• Updated the end-of-combat gold drop message to be accurate (it was still showing the amount of gold per character rather than for the full party).
  
• Improved the rendering code. Large zones with many buildings, like the Grand City, will perform better on older hardware now.
  
• Added messages to the demo version to make it clear when an exit to another zone is only available in the full version.
