Tiny Demo Patch

Hello,

A few issues updated in Demo:

• Crash caused by a rare sound load error is fixed
  
• Crash caused by extreme time values encountered by having too many Crises in queue is fixed
  
• Crash caused by a corner case drag and drop movement of Hero buttons fixed.
  
• Wrong display of Shielded attacks during some late-game crises with Unblockable attacks fixed.
  
• Fixed issue causing main window remaining unfrozen (showing popups etc) when opening Map menu via Bonus.
  

Have a nice day,

Ondrej
