Beta 3

• Fixed the minimize problem
• Added the UltraFast option
• Added the Smart! Sensitivity slider

This slider, which can be found in the Preferences window, will let you fine-tune how sensible should the Smart! option be.
There're no guidelines for the optimal setting... simply play with it and leave it where you feel it work best for you.

• Fixed several bugs
• Removed the Learn Mode option
• Added support for the sound effects (again... hope this time works!)
