Renamed Phaser.BitmapFont to Phaser.RetroFont because I believe it will cause confusion otherwise. Also tidied up the asset fonts folder.
Tween.generateData(frameRate) allows you to generate tween data into an array, which can then be used however you wish (see new examples)
Added new Retro Font examples.
PIXI + Phaser Definitions 


Thanks to @natelong for Maintaining the original PIXI definitions.

Updated to 1.5.2 PIXI. 

Needs testing. May be missing updates from the dev branch of Phaser 1.2 that occurred in the last few days.  

Warning! I made Phaser.point extend PIXI.Point. It was the only way I could get this to work. 

If class property position is PIXI.Point
And you try to overlay position with Phaser.Point

I get "X cannot extend Y type mismatch" for a whole bunch of classes. Only when I extend PIXI.Point does the errors dissapear. 

Also was not sure to include PIXI in this file or a separate one.
Group.xy(index, x, y) allows you to set the x and y coordinates of a Group child at the given index.
Group.reverse() reverses the display order of all children in the Group.
New labs demo.
Fixed some Easing docs issues.
New build files.
Labs code updates.
Merge pull request #507 from clark-stevenson/patch-1

PIXI + Phaser Definitions
Tilemap.putTile now correctly re-calculates the collision data based on the new collideIndexes array (fixes #371)
Tilemap.putTile can now insert a tile into a null/blank area of the map (before it could only replace existing tiles)
Adding in TweenGroup for wip dev.
Added Phasers new Physics Manager and restored the pre-1.1.4 ArcadePhysics system. The new manager can handle multiple physics systems running in parallel, which could be extremely useful for lots of games.
Testing map collision
Testing lines.
New split physics system is implemented. Still tidying-up, but ArcadePhysics, P2 and Ninja Physics are in and configured. Lots more examples required, and tilemap collision mostly broken in Arcade at the moment. Time to implement in Ninja.
Added in Circle to the Ninja physics system.
New tiles and new map test.
Fixed gruntfile and included new labs demo.
Phaser.Image extends PIXI.Sprite
InputHandler.enableSnap now correctly assigns the snap offset parameters (fixes #515)
Updated tilemap type to string (fixes #516)
Fixed typo in README (thanks prtksxna, #518)
