-[SPINE] Separates the PIXI.Spine portion into its own file, allows for easier spine.js library updates. Implements new loading system, IK, per bone flip and skinned mesh attachments.

-[SPINE] Spine.js file only contains the spine runtime, modifications needed made it to the official library. https://github.com/EsotericSoftware/spine-runtimes/pull/315

If the BaseTexture dimensions don't match the texture frame then we need a new texture anyway because it's part of a texture atlas

added default blend mode to strip

Fixed blendmode in Srip

swapped b & c in TilingSprite and Graphics getBounds

Fixing issue #1038 ...

Moving anchor point to translate instead of fillRect. Fix for https://github.com/GoodBoyDigital/pixi.js/issues/1038

fixed non po2 tiling texture bug

Fixed Strip Alpha bug

removed the renderStrip function from CanvasRender

Added some documentation for Rope.js ...

Conflicts:

Fixed strip render bug

removed texture check from render loop ...

saved on if statement! better than none :)

Removed update and destroy webGL functions

Rewrote update transform ...

matrix now used correctly.

Added Canvas Renderer resolution

Merge pull request #908 from alvinsight/dev ...

Removed if(true) in Strip ;)

Removed silly whitespace to pass jsHint

Removed if(true) in Strip

A tiny bit of docs

TilingSprite._renderWebGL: missing mask argument in renderSession.maskManager.popMask call

Remove trailing commas from object property lists ...

Removing trailing commas for:
- internal consistency;
- compatibility with the Google Closure compiler defaults.

The Google Closure compiler assumes ECMAScript 3 and emits errors when
parsing objects with trailing commas in their property list.
(Compilation succeeds if the user manually specifies ECMAScript 5.)

Tied up new webGL batch approach ...

now 400% faster when dealing with separate textures

Merge branch 'master' of https://github.com/GoodBoyDigital/pixi.js

code republish + linted

Fixed TilingSprite so it can now use a trimmed frame from a texture atlas as its source (even animated in canvas, not in WebGL yet). ...

Tidied up the source to match Pixi elsewhere.
Removed dead onTextureUpdate method.

Removed context path settings as not required for a fillRect.

updateFrame removed ...

Commented out the updateFrame variable from DisplayObjects

Merge branch 'Graphics-upgrade' into dev ...
