Loads of updates across most the Tilemap files. Not finished yet, still CSV loading to do and a multi-tileset issue to resolve, but it's a lot more flexible now.
All the Debug methods have had the word 'render' removed from the start. So where you did `debug.renderSpriteInfo` before, it's now just `debug.spriteInfo`.
Debug methods that rendered geometry (Rectangle, Circle, Line, Point) have been merged into the single method: `Debug.geom`.
Fixed issue where renderOrderID wasn't being assigned correctly, causing the Input Handler to be unable to select the "top" item on a display list (would all default to zero)
Fixed issue where Stage would assign renderOrderIDs in reverse, should be in sequence.
Fixed issue where objects where checking World for the currentRenderOrderID by mistake instead of Stage.
Basically, input handling works a lot better now for Groups and nested objects :)
Group.sendToBottom(child) is the handy opposite of Group.bringToTop()
Group.moveUp(child) will move a child up the display list, swapping with the child above it.
Group.moveDown(child) will move a child down the display list, swapping with the child below it.
New build script now cleanly splits Phaser, Pixi and p2 so they are each UMD wrapped and each available in the global scope (now more requireJS friendly!).
phaser-no-libs.js allows you to use your own version of p2.js or pixi.js with Phaser. Warning: This is totally unsupported. If you hit bugs, you fix them yourself.
Fixed silly instanceof bug in game objects (sorry guys).
If the game was set to NO_SCALE and you swapped orientation, it would pause and resize, then fail to resize when you swapped back (thanks starnut, fixes#258)
You can now safely destroy a Group and the 'destroyChildren' boolean will propogate fully down the display list.
Calling destroy on an already destroyed object would throw a run-time error. Now checked for and aborted.
Calling destroy while in an Input Event callback now works for either the parent Group or the calling object itself.
In Group.destroy the default for 'destroyChildren' was false. It's now `true` as this is a far more likely requirement when destroying a Group.
All GameObjects now have a 'destroyChildren' boolean as a parameter to their destroy method. It's default is true and the value propogates down its children.
Phaser.Timer.stop has a new parameter: clearEvents (default true), if true all the events in Timer will be cleared, otherwise they will remain (fixes#383)
AnimationManager.add documentation said that 'frames' could be null, but the code couldn't handle this so it defaults to an empty array if none given (thanks yig)
Also updated TypeScript definitions and StateManager.add docs.
