Bug fixing, the never ending story

Fixing bugs, do they ever finish? :-)

All binaries should be at skydrive 

BB)

• New Engine.Debug property (it set all related sprites to debug)
• TLayer.Trace() could raise a AV since under certain conditions a cell can be null 
• Events from sprites moved to their own new class TEvents 
• Screen buffers size is now a property

HBF)

• Final boss getting better
• When final boss dies he liberates the key
• Final boss has a new sound when flapping the wings
• SpriteFactory now gets IGameServices rather than many properties
• Arrows behave better against bullets
• New enemy mine, it  has a gravity factor of 2 and kills Enemies
• Finally rays have a pillar 
• New trigger method ItemOffset() in order to change the current tile
• Die sound is more calm (it was too loud)
• New horizontal trap doors
• Bomb has a gravity factor of 2
• One can observe the rendered tiles (used in final boss for heating ice)
• New method PreciseCollideAgainstTiles(): bool which tests 8 precise collisions
• GravitySwitcher now publishes Flashing and Quake duration properties
• Mirror checks for obstacles (if there is an obstacle then the sprite cannot be mirrored)
• Stalactite, flame and wall now  properly check for collisions (not only for spatial partitioning)
• Droid,eye and final boss heats the special ice cubes and also mechanic enemies
• Eye now publishes initial angle and laser color 
• Arrows are now enemies
• Candle vanish slowly
• New Focus element (used in Colors screen)
• Focus color can now be set as and mask via DirectColor attribute
• Spotlight now slows down also enemies
• Published attributes can now also be enumerators
• Spider web when touching sprites they get locked until the web disappears
• SLOW_VAR removed, instead SpeedFactor is used
• Runes are now shown in the achievements menu and not in the hud
• Observers are cleared properly otherwise AV
• Candle new property off so when true it won't emit light when in darkness 
• A bit clever approach for the sounds pool
• Fixed a small issue with the steps when taking the key 
• Now when the default resolution does not work, the game properly restarts at 1024x768
