 * The Grunt script has been updated to enhance the intro / outro and Pixi defaults. Pixi has been split into intro / outro and main blocks, so you can exclude its intro cleanly. The excludes are now bound, so if you exclude the Phaser UMD it will do the same for Pixi as well (thanks @spayton #2192)

 * There is new documentation on building Phaser for Webpack and a new custom build grunt option (thanks @deiga #2331)
