Polygon class & drawPolygon method
Tidying up some docs.
Updated to latest version of Pixi.js. Lovely new WebGL filters now working happily :)
Tracked down an evil bug in Group.swap that caused the linked list to get corrupted in an upward (B to A) neighbour swap.
Fixing up Group.sort
Added Group.sort, can sort the Group based on any given numeric property (x, y, health), finally you can do depth-sorting :)
Added in a Group.sort demo, also updated the documentation and build files.
Implementing PluginManager.remove function, added PluginManager.removeAll function.
