melonJS 1.1.0 beta 3

• fixed default collision bounds when no collision shapes are defined
• fixed quadtree debug mode drawing (debug Panel)
• fixed the strokeArc and fillArc function from the canvas renderer
• fixed shape drawing in debug mode when several shapes are defined
• optimized temporary object creation in the quad tree implementation
• Lowered memory usage for the quad tree by adding a simple object pooling mechanism
• fixed the maxChildren and maxDepth parameters when creating the quad tree, and increased maxChildren default value to 8
• fixed a regression on the spritewidh/spriteheight properties (supposed to be optional)
• entity body objects are now properly relative to their parent container
• fixed polygon collision shape position when converted from a rectangle shape with an offset position
• fixed a regression in me.video.getPixelRatio (was throwing an exception if called before me.video.init)
• fixed bounds creation for default collisionMap
• updated the collision test example to use ellipse based collision shape rather than rectangle
• updated the stroke* functions to accept a linewidth param.
• clarified the documentation for the setCollisionMask function
